Feature: Convert regex to AQS in search bar

### What's the Problem?

Search queries can be even more powerful leveraging regular expressions.
Instead of the clunky Windows Query Syntax we could move from
```
.exe OR .pdf
to
\.exe|\.pdf
```
and queries like
```
path/to/*/something
```

### Solution/Idea

Add a checkbox to choose between windows default and regexp.
Also allow making regexp the standard.
