[Feature] Include/exclude searching in files whose name match some regex

[onox]

Is your feature request related to a problem? Please describe.
It seems possible to only search in files that have a specific extension, but it's not possible to (exclude) search in files that start/contain a specific string or are in some specific folder.

Describe the solution you'd like

• Be able to only/exclude search in files that start with some string or match some regex. For example, only search in files a-*.ads or exclude *_test.cu (like [Feature] Add filters for text in file names #13)
• Be able to exclude files that are in some folder at an arbitrary depth. For example exclude files in ./**/test/ or ./**/examples/**/ (** here means a hierarchy of one or more folders)
