WebStorm: search does not work

As lena said, the following should fix it for you:

1. Click File -> Invalidate Caches / Restart..
2. Click the button "Invalidate and Restart"
3. After restart, try run the search again

For me nbaosullivan's proposed solution didn't work.

In my case Recursive(Alt+Y) options wasn't selected. I selected it and it worked and it will be set as default, you don't need to select it all the time.

Try this (it helped me in PhpStorm 2019.3.1 when "Invalidate Caches / Restart" did not):

1. Close WebStorm

2. Backup directory <your project>/.idea/ to anywhere

3. Delete file <your project>/.idea/modules.xml

4. Open WebStorm
