Suggested March 2024 What Is Search Indexing And How Does It Affect Searching In Windows 11/10?

The Windows Search function makes the task of finding files and folders on your Windows PC incredibly fast but sometimes the function may fail to work as desired. Many believe, this occurs mainly when Windows starts indexing files. Is it true? So, what is indexing in Windows 11/10 and how does it affect Search function?

What is Seach Indexing in Windows 11/10

In Windows OS, the process of looking at files, email messages, other content on your PC and cataloging their information, such as the words and metadata in them is termed Indexing. Indexing the contents stored on your PC helps you get results faster by looking at an index of terms. Initially, when the Indexing process runs, the process can take up to a couple of hours to complete. Thereafter, it silently runs in the background of your PC and simply re-indexes updated data. Let us take a look at the following aspects:

How does indexing affect Search in Windows 10?

Types of files that can be indexed

How much of a file’s information is indexed?

How much space is used by the index?

Where is the index information stored?

Why does indexing always run on a PC?

1] How does indexing affect Search in Windows 11/10

Much like an index of a book, a well-made digital index can help quickly direct the user to the information he is looking for by scanning for common properties. Besides, it will return with the most valid results in seconds. In the absence of Indexing, the process could take minutes, for the same operation to complete. Thus, Indexing speeds up the search results!

On the other hand, many apps in the Microsoft Store too, depending on the index to provide up-to-date search results for your files and other content. Disabling indexing for Microsoft Store may result in the apps running either slowly or not working at all. It depends on how heavily these apps rely on the Indexing feature.

Choosing not to index the contents of files can reduce the size of the index. However, it may make the process of finding files harder.

2] Types of files that can be indexed

In addition to files bearing names, files showing some properties or metadata present in some binary format such as DOC or PDF can be indexed. The ‘File Types‘ tab of ‘Advanced Indexing Options‘ can be used to include or exclude certain file types from search and their contents and properties. To see how it is done, see our post on Windows Search Indexer and Indexing Tips & Tricks.

Also, apps you choose to install to your PC can add their own information to the index to speed up searching. Services such as Outlook adds all emails synced to a machine to the index by default. It uses the same index for searching within the app.

All the properties of your files including file names and full file paths are indexed, by default.

3] How much of a file’s information is indexed?

There are two ways via which you can decide how much of a file can be indexed –

Properties only

Properties and content

For the former, indexing will not look at the contents of the file. It will just allow searching by file name.

4] How much space is used by the index?

The indexing process can take up available space if there are lots of files that are small in size. The index size will increase dramatically in proportion to the size of the files.

Under a usual scenario, the index will be less than 10% of the size of the indexed files. For example, if you have 1GB of text files, the index for those files will be less than 100 MB.

5] Where is the index information stored?

All the information or data gathered via Indexing is stored locally on your PC at the following location:


If required you can change the location of the Windows Search Index.

None of the information is sent to Microsoft or outside your computer. However, apps you choose to install on your PC can have access to the data in your PC’s index. It is, therefore, necessary to be careful while installing something from outside. The best is to make sure that the source is a trusted one.

Windows.edb is the database file of the Windows Search service, which provides content indexing, property caching, and search results for files, e-mail, and other content.

6] Why does always indexing run on a PC?

The purpose of indexing is to constantly track changes made to the files and update itself with the latest information. As such, it can open recently changed files, identify the changes made to it, if any and update the index with the latest information. But at times, the Search Indexer is reported to consume High Disk or CPU usage.

What Is Latent Semantic Indexing And Why It Doesn’t Matter For Seo

Many claims are made for Latent Semantic Indexing (LSI) and “LSI Keywords” for SEO.

Some even say that Google relies on “LSI keywords” for understanding webpages.

This has been discussed for nearly twenty years and the evidence-based facts have been there the entire time.

This Is Latent Semantic Indexing

Latent semantic indexing (also referred to as Latent Semantic Analysis) is a method of analyzing a set of documents in order to discover statistical co-occurrences of words that appear together which then give insights into the topics of those words and documents.

Two of the problems (among several) that LSI sets out to solve are the issues of synonymy and polysemy.

Synonymy is a reference to how many words can describe the same thing.

A person searching for “flapjack recipes” is equal to a search for “pancake recipes” (outside of the UK) because flapjacks and pancakes are synonymous.

Polysemy refers to words and phrases that have more than one meaning. The word jaguar can mean an animal, automobile, or an American football team.

LSI is able to statistically predict which meaning of a word represents by statistically analyzing the words that co-occur with it in a document.

If the word “jaguar” is accompanied in a document by the word “Jacksonville,” it is statistically probable that the word “jaguar” is a reference to an American football team.

By understanding how words occur together, a computer is better able to answer a query by correctly associating the right keywords to the search query.

The patent for LSI was filed on September 15, 1988. It’s an old technology that came years before the internet as we know it existed.

LSI is not new nor is it cutting edge.

LSI preceded the internet and was created during a time when Apple computers looked like this:

LSI was created when a popular business computer (IBM AS/400) looked like this:

LSI is a technology that goes way back.

Just like computers from 1988, the state of the art in Information Retrieval has come a long way over the past 30+ years.

LSI is Not Practical for the Web

A major shortcoming of using Latent Semantic Indexing for the entire web is that the calculations done to create the statistical analysis have to be recalculated every time a new webpage is published and indexed.

This shortcoming is mentioned in a 2003 (non-Google) research paper about using LSI for detecting email spam (Using Latent Semantic Indexing to Filter Spam PDF).

The research paper notes:

“One issue with LSI is that it does not support the ad-hoc addition of new documents once the semantic set has been generated. Any update to any cell value will change the coefficient in every other word vector, as SVD uses all linear relations in its assigned dimensionality to induce vectors that will predict every text samples in which the word occurs…”

I asked Bill Slawski about the unsuitability of LSI for search engine information retrieval and he agreed, saying:

“LSI is an older indexing approach developed for smaller static databases. There are similarities with newer technologies such as the use of word vectors or word2Vec.

One of the limitations of LSI is that if new content is added to a corpus that indexing for the entire corpus is required, which makes it of limited usefulness for a quickly changing corpus such as the Web.”

Is There a Google LSI Keywords Research Paper?

Some in the search community believe Google uses “LSI Keywords” in their search algorithm as if LSI is still a cutting-edge technology.

To prove it, some refer to a 2024 research paper called, Improving Semantic Topic Clustering for Search Queries with Word Co-occurrence and Bigraph Co-clustering (PDF).

That research paper is absolutely not an example of Latent Semantic Indexing. It’s a completely different technology.

In fact, that research paper is so not about LSI (a.k.a. Latent Semantic Analysis) that it cites a 1999 LSI research paper ([5] T. Hofmann. Probabilistic latent semantic indexing. …1999) as part of an explanation of why LSI is not useful for the problem the authors are trying to solve.

Here’s what it says:

Short texts however – such as search queries, tweets or instant messages – suffer from data sparsity, which causes problems for traditional topic modeling techniques.”

It’s a mistake to use the above research paper as proof that Google uses LSI as an important ranking factor. The paper is not about LSI and it’s not even about analyzing webpages.

It’s an interesting research paper from 2024 about data mining short search queries in order to understand what they mean.

That research paper aside, we know that Google uses BERT and neural matching technologies to understand search queries in the real world.

Long story short: the use of that research paper to make a definitive statement about Google’s ranking algorithm is sketchy all around.

Does Google Use LSI Keywords?

In search marketing, there are two kinds of trustworthy and authoritative data:

Factual ideas that are based on public documents like research papers and patents.

SEO ideas that are based on what Googlers have revealed.

Everything else is mere opinion.

It’s important to know the difference.

Google’s John Mueller has been straightforward about debunking the concept of LSI Keywords.

There’s no such thing as LSI keywords — anyone who’s telling you otherwise is mistaken, sorry.

— 🍌 John 🍌 (@JohnMu) July 30, 2023

Noted search patent expert Bill Slawski has also been outspoken about the notion of Latent Semantic Indexing and SEO.

Bill’s statements on LSI are based on a deep knowledge of Google’s algorithms, which he has shared in fact-based articles (like here and here).

Bill Slawski Tweets His Informed Opinion on Latent Semantic Indexing


— Bill Slawski ⚓ (@bill_slawski) August 18, 2023

Those terms have their own technology and processes behind how they are determined, and do not use LSI. There is nothing “latent” about them. 3/3

— Bill Slawski ⚓ (@bill_slawski) August 18, 2023

Why Google Is Associated with Latent Semantic Analysis

Despite there not being any proof in terms of patents and research papers that LSI/LSA are important ranking-related factors, Google is still associated with Latent Semantic Indexing.

One reason for this is Google’s 2003 acquisition of a company called Applied Semantics.

Applied Semantics had created a technology called Circa. Circa was a semantic analysis algorithm that was used in AdSense and also in Google AdWords.

According to Google’s press release:

Semantic Analysis & SEO

The phrase “Semantic Analysis” was a hot buzzword in the early 2000s, perhaps partially driven by Ask Jeeves’ semantic search technology.

Google’s purchase of Applied Semantics accelerated the trend of associating Google with Latent Semantic Indexing, despite there being no credible evidence.

Thus, by 2005 the search marketing community was making unsubstantiated statements such as this:

“For several months I’ve noticed changes in website rankings on Google and it was clear something had changed in their algorithm.

One of the most important changes is the likelihood that Google is now giving more weight to Latent Semantic Indexing (LSI).

The SEO myth that Google uses LSI Keywords quite possibly originated from the popularity of phrases like “Semantic Analysis,” “Semantic Indexing” and “Semantic Search” having become SEO buzzwords, given life by Ask Jeeves’ semantic search technology and Google’s purchase of semantic analysis company Applied Semantics.

The Facts About Latent Semantic Indexing

LSI is a very old method of understanding what a document is about.

It was patented in 1988, well before the internet as we know it existed.

The nature of LSI makes it unsuitable for applying across the entire internet for purposes of information retrieval.

There are no research papers that explicitly show that latent semantic indexing is an important feature of Google search ranking.

The facts presented in this article show that this has been the case since the early 2000s.

Yet Googlers have affirmed multiple times that Google uses no such thing as LSI Keywords.

Let me say it again louder for those at the back: There is no such thing as LSI Keywords.

Considering the overwhelming amount of evidence, it is reasonable to assert that it is a fact that the concept of LSI Keywords is false.

The facts also indicate that LSI is not an important part of Google’s ranking algorithms.

What Is Host Process For Windows Tasks Or Service Host In Windows 11/10

Whenever we face some performance issues with our computer, the first thing we do is open up the Task Manager, and then look for the applications or components which are using the most resources. If you are familiar with Task Manager, then you must have also noticed that at times, the ‘Host Process for Windows Tasks’ or ‘Service Host’ process consuming resources. What these processes and what can you do if your Host process has stopped working or consumes high CPU, Disk or Memory usage.

Host Process for Windows Tasks or Service Host

Windows is essentially working just because of its Services. A large number of services running the background facilitate your daily tasks and operations. Some of these services are compiled into EXE files, and they are complete in themselves. These services show up in the Task Manager. But some services are written in DLL files, and they cannot be executed directly. Microsoft shifted to DLL files as they were easy to maintain and update from a programming point of view. DLL services require a host process, an EXE that can execute them and this is what ‘taskhost’ in Windows is.

Taskhost in Windows 11/10 is a core file located in the System32 folder and has been renamed as ‘ chúng tôi ’, from ‘ chúng tôi ’ in Windows 7. If you find a file with this name in any other location, it could well be a virus and you might want to get it checked with your security software.

Each ‘Host Process for Windows Task’ is an instance of ‘taskhost’ running some service in the background. Although Windows Task Manager does not exactly let you view what services it is running, other tools can.

Host Process for Windows Services has stopped working or consuming High resources

If you see a ‘stopped working’ message box, you can try the following troubleshooting suggestions:

Perform Clean Boot and troubleshoot the issue manually.

There might be times when you find that this process is using high resources. You can now understand that this is caused due to the underlying service and not the process itself. Also, you might notice high consumption of resources at Windows startup. That is just because the taskhost is loading all the DLL files and schedule to run them. Once it is completed, the usage will settle down to a lower value and will remain pretty low for the rest of the time.

I mentioned earlier that the Task Manager does not let you view the underlying services. But you can use Process Explorer from Microsoft to view the services beneath the taskhost. It is a portable utility, and you can run it directly after downloading. You can use this tool to view all the details associated with the taskhost.

Find ‘taskhostw.exe’ in the left pane, and you can read all the details in the lower pane. Another way to view the list of DLL files loaded by taskhost is by typing in the following command in a cmd window:

tasklist /M /FI "IMAGENAME eq taskhostw.exe

This command will list all the DLL files that were loaded by this process on Windows Startup. If you go through the list, you will find out some essential files that provide core functionality to Windows.

So, in a nutshell, Taskhost is a core Windows process that provides functionality to load and execute dynamic link libraries. Since it hosts various DLL files, sometimes it can consume resources at a more than normal rate. If you are facing any such issues where the process has stopped responding or is using a lot of resources. Use the Process Explorer, Performance Monitor and Resource Monitor, and try to troubleshoot the problem manually.

Guide: What Is Personal Voice On Iphone, Ipad And Mac? How Does It Work?

Personal Voice lets folks with ALS train an iPhone, iPad or Mac to simulate their voice, which is more affordable than the time-consuming voice banking process.

Personal Voice enables you to replicate your own voice after just fifteen minutes of audio training on your iPhone, iPad or Mac.

Reading aloud a randomized set of text prompts is all it takes to create a computer voice that sounds eerily similar to your own.

You can use this voice with a feature called Live Speech to have anything you type out spoken out loud in your synthesized voice instead of a Siri one.

What is Personal Voice? How does it work?

Personal Voice is a new accessibility feature available on the iPhone, iPad and Mac with iOS 17, iPadOS 17 and macOS 14. By leveraging machine learning, it can create a computer voice that sounds just like your own—without relying on specialized equipment and a time-consuming process known as voice banking.

You could also use the feature to clone the voice of a loved one to use when they’re deceased as a way of memorializing them. By following randomized prompts that guide you to speak specific sentences aloud, your iPhone, iPad or Mac can replicate your voice with just fifteen minutes of audio training.

Introducing Live Speech

But it goes beyond that. Another new accessibility feature in iOS 17, dubbed Live Speech, can use your synthesized voice during cellular and FaceTime calls, as well as in-person conversations. Your Personal Voice model preserves vocal fidelity by imitating your accent, tone, inflection and cadence.

For those who no longer speak with the clarity they once did, Live Speech is a great way to type out a greeting, an order or whatever you’d like and have the device speak it out loud in a way that sounds like you. To save time, you can pre-write phrases and remarks to play aloud with a touch.

Who should use Personal Voice and Live Speech?

Apple designed Personal Voice and Live Speech to “support millions of people globally who are unable to speak or who have lost their speech over time,” including those diagnosed with amyotrophic lateral sclerosis (ALS) or other conditions that can progressively impact speaking ability.

Personal Voice and Live Speech requirements

Here’s what you need to use the Personal Voice feature:

iPhone with iOS 17.0 or later

iPad with iPadOS 17.0 or later

Apple silicon Mac with macOS 14.0 or later

Personal Voice is available in English but will expand to other languages over time.

Personal Voice and your privacy

But does Personal Voice protect your privacy? According to Apple, privacy is guaranteed because all processing is done directly on your iPhone, iPad or Mac.

Apple can’t listen to your voice recordings. Furthermore, samples aren’t shared with other companies nor uploaded to Apple’s servers. You can, however, give explicit permission for secure syncing of your Personal Voice model via iCloud.

How to create a Personal Voice model to clone your voice

You’ll need to read aloud a set of randomly chosen voice prompts to create a sound-alike voice. The feature needs about 15 minutes of audio training to reliably make a synthesized voice for text-to-speech that sounds just like you. You don’t have to sit through the whole fifteen minutes at once.

If you don’t have time to finish the process in one sitting, you can pick up where you left off later. Your iPhone, iPad or Mac will then analyze voice recordings to create your Personal Voice model, but this will take time.

Even though Apple’s devices are equipped with a dedicated coprocessor to run deep neural networks in a battery-friendly way, called Neural Engine, you may need to leave your device plugged in overnight to chew through all those samples.

Your Personal Voice model is saved to the device you created it on, meaning you’ll need to repeat the training process to create similar voice profiles on your other devices. However, you can give explicit permission for your voice profile to be synchronized and shared between devices with end-to-end encryption.

ALS and voice banking

ALS impacts one’s speaking ability as muscles in the throat and mouth progressively weaken. People with ALS often undergo a time-consuming process called voice banking to create a digitized version of their own voice. With Personal Voice, anyone can clone their voice just by reading through pre-crafted prompts.

To learn more about this condition, visit the ALS website.

AAC apps embracing Personal Voice

“If you can tell them you love them, in a voice that sounds like you, it makes all the difference in the world—and being able to create your synthetic voice on your iPhone in just 15 minutes is extraordinary,” Green added.

Your Personal Voice model is available not only in Apple’s apps but also in specialized augmentative and alternative communication (AAC) apps from third-party companies like AssistiveWare.

iOS 17 is launching this fall

Apple will preview iOS 17 and other updates at WWDC, with the first developer-only beta of iOS 17 arriving following the June 5 keynote. Some weeks later, the general public will be able to install iOS 17 and take Personal Voice for a spin.

The company will continue releasing developer and public betas of iOS 17 and other operating system updates throughout the summer. iOS and iPadOS 17 should release publicly this fall before the next iPhone arrives.

Personal Voice turns typed text into speech using your synthesized voice.
