Windows 10 Start Menu Search not searching or working
Starting with Windows v1903, the OS offers two types of searches — Classic and Enhanced search. We either need to add more folders to classic search or use enhanced mode.
1] Enable Enhanced Mode
You need to enable the Enhanced Search Mode, and configure the folders you want to be indexed.
2] Add Folders to Class Search
If you do not want to use Enhanced search, then it’s a good idea to add folders which are important for you. You need to configure the Search Indexing Options. Go to Settings > Search > Classic > click on Customize search locations here.
In the pop-out window which it opens, click on Modify, and add drives and folders were your most important folders are available. Once indexing is complete, Windows will be able to find the file and display in the result.
3] Remove excluded folders
If you are using Enhanced mode, but your files are still not appearing, then you should look at the excluded folder list. Under Search, there is a list of folders under the Excluded folder list. Click on the one you want to remove, and then click on the button which says Remove Excluded folders.
When using Classic search, you need to check if the index has restriction on the file type. It is available in Advanced options > File Types. If you want to search into documents, you can also enable the Index Properties and File Contents. It should resolve the Windows not able to search for a fil on PC problem.
4] Run Windows Indexer Troubleshooter
If nothing works, it is about time that you use the Search Indexer Troubleshooter. It is available at the end of the Search settings. It will prompt you with a few questions, and take appropriate action. Hope these tips help you resolve your problem. Helpful post: Windows Search Indexer is not working.
