phpstorm search everywhere is not working, do you know the solution?

Please run File > Invalidate Caches/Restart > Invalidate and Restart and check the issue after that. 

There's a similar problem going on, it's fixed and the fix will be included in the next EAP build + in the next major IDE update.

Are it it already included? I has Build #PS-221.5921.28, built on June 22, 2022 and has same issue(search not working on some functions) but File > Invalidate Caches/Restart > Invalidate and Restart help me

Please try to update your IDE installation to the most recent available build (2022.2.3). Would the issue be reproducible there?

Looking at your screenshot: based on the fact that ALL files in the project tree have that sort of "dirty yellow" background color... it looks like ALL of your files are considered excluded / outside of the project for some reason.

Most likely a user error of some kind. E.g. you may have opened it from a different path (i.e. when symlink is involved), may have c=misconfigured it later somehow (marked folder as Excluded by mistake or whatnot) or maybe even some sort of config file corruption (pretty unlikely).

Anyway, please do this:

1. Close your project
2. Go to the project root folder and delete your .idea subfolder (that's where your project settings are stored).
3. If you have that project still visible in the IDE (Recent Projects on the Welcome screen) -- you may remove it there as well (to avoid any possible confusion).
4. Now create a new project in PhpStorm from scratch using existing files: just use "Open" and point to the folder with your project.
