How to set up
After installing the extension, the tool window can be opened from View >> qgrep Search Tool. It also comes with a shorcut already assigned (Alt+Shift+F), but if it's already assigned or you want to change it, you can do that from Tools >> Options >> Environment >> Keyboard, the command name is View.qgrepSearchTool.
After opening the tool window, you have to set up the folders that will be indexed:

If your projects have a format that can be parsed by MSBuild, you can use the Gather from solution button to automatically grab all the folders and file extensions from the solution.
If you make changes to your files and want the changes to be visible in the search results, you have to reindex manually using the buttons from the lower right corner of the tool window.
Features overview
Search Results
The search results can be shown as list or grouped by file, there is also a contextual menu.

History
The history keeps all of your recent searches but it can also show all of your recently opened files from inside the tool.

Advanced search configurations

Open file
You can also search for files using unordered keywords, using a different window that can be opened from View >> qgrep Open File or using the shortcut (Alt+Shift+I). You can change this shortcut as well, the command name is View.qgrepSearchFile.
