Searching for files in the repository depends on the order of the searched words

Summary

Searching for files in a repository does not show all files.

Steps to reproduce

1. Open https://gitlab.com/freepascal.org/lazarus/lazarus

2. Click button Find file

3. Type res vi. You will see in the first line the file: ide/searchresultview.pp.

4. Continue to type sear (to get res vi sear). This file will disappear from the list even though it contains that word.

5. At the same time, the file will reappear if you change the word order

What is the current bug behavior?

A file that includes all of the searched words in its name does not appear in the results.

What is the expected correct behavior?

I understand that a "smart" search is being used, but it should expand the number of results (or reorder), not decrease them.
