PyCharm: Ctrl+F not able of finding substrings (only full strings)

I'm not sure why but I was sure that Ctrl + F can find all occurrences of a string in a file.

Say I want to find all occurrences of variables that ends with _cfg or all imports ending with time in a file and it turns out that Ctrl + F is not able to find it.

It can only find full strings such as user_cfg or datetime but not when you put a substring of the name into the search fields.

Is there any option that I can turn on full substring search in a file?

I tried testing with multiple substrings.

Solution

This is usually caused by having Words activated. Try toggling it and see if that helps.

(On Windows it's Alt+W or clicking the W next to the search string. Not sure what it looks like on Mac.)
