How Latest Visual Studio 2022 Update Speeds Code Search

The recently released Visual Studio 2022 17.1 Preview 3 improves code search even more than gains made in the jump from VS 2019 to VS 2022.

As we reported in September 2021 coverage of VS 2022 17.0 Preview 4, Find in Files was already 3x faster when searching large solutions.

According to a new Jan. 26 post on Microsoft's developer blogs site, the dev team is continuing to boost the search performance.

"Visual Studio 2022 Find in Files is already more than 2x faster for 95 percent of searches compared to Visual Studio 2019," said product manager Denizhan Yigitbas. "We wanted to make code search even better. I am excited to announce that Visual Studio 2022 17.1 Preview 3 introduces indexed Find in Files to make your search experience even faster!"

The functionality is enabled by going to Tools > Options > Environment > Preview Features and verifying that "Enable indexing for faster find experience" is checked.

Here's the explanation for how the indexing boost works:

At solution load or folder open, Visual Studio launches a satellite process "ServiceHub.IndexingService.exe" and transmits a list of files to it to index. The indexer then scrapes through the files and constructs an index of all of the n-grams contained in each file.

When the user performs a "Find," this index is used to prune files from the search so that it completes more quickly.

The indexing process avoids impacting solution load, build and user activities by running at Below Normal operating system priority outside of the main Visual Studio process.
