Suggestion search: Case sensitive, wildcard, inverse

I wonder if we can have an advanced search feature? This could include:

- Search with/without capital letters
- Placeholder *
- Inverse search (not to search files which have the words included, but for those who don´t have them included). This is because often you don´t know the exac filename but you know exactly which words it does NOT contain.

You have that already...

In the quick search? How does it work?
