The indexing service is useful for us when we try to locate something. But some people report that something wrong happened with the indexing service. To figure out this issue, this article on MiniTool Website will tell you how to resolve the issue that Windows 10 indexing is not running.

What Is Search Indexing?

In relational databases, an index is a single, physical storage structure that sorts the values in one or more columns of a database table. It is a collection of values in one or more columns of a table and a corresponding list of logical Pointers to the data page in the table that physically identifies those values.

When there are a large number of data, the first method of searching for information is a full table search that takes out all the records one by one, compares them with the query conditions, and returns the records that meet the conditions, which consumes a large amount of system time and causes a large number of disk I/O operations.

The second method is to create an index in the table, then find the index value that matches the query criteria in the index, and finally find the corresponding record in the table through the ROWID (equivalent to the page number) saved in the index.

With the help of search indexing, you can get the most valid and up-to-date results in seconds; otherwise, the searching process could take minutes, for the same operation to complete.

But at the same time, search indexing has some cons you may pay attention to:

1. 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.

2. When the data in the table is added, deleted, and modified, the index also needs to be maintained dynamically, which reduces the speed of data maintenance.

Windows 10 Indexing Is Not Running FAQ

Why does Windows indexing keep pausing?

Indexing is paused by local battery-saving policy – according to some affected users, this issue is often created by a local group policy called 'Prevent indexing when running on battery power. If this policy is enabled, the indexing function will automatically be disabled while you're in battery-saving mode.

Why is your indexing taking so long?

If you have a lower-powered computer with an older, slower hard drive, indexing can place a burden on the system resources, resulting in slower all-around performance as well. If you spend most of your time online working with data that is stored on the internet, the indexing burden should be pretty minimal.

Is disabling indexing good?

Disabling indexing will increase the time it takes for Windows and other apps to return search results. So, if you have a fast CPU and a standard hard drive, you can keep indexing on. Since hard drives are slow to read, Windows will take longer to search for files without indexed data.

Is indexing the same as searching?

The index is where your discovered pages are stored. After a crawler finds a page, the search engine renders it just like a browser would. In the process of doing so, the search engine analyzes that page's contents. All of that information is stored in its index.
