I'm currently working on a project, which in total has 1371556 lines in 5142 files and the global search seems to be completely non-functional.

Using ctrl+f works as expected in a single file and Find References To Symbol Under Cursor does as well, but if I try to search in all files the whole system doesn't do anything.

If I try to search in a project with fewer lines and files 326109 lines in 1137 files, the search works fine again.
