### Steps to reproduce

1. search for a folder (e.g "files"
2. select some completion from the keyboard or (adding a space at the end after a word) (eg. "files ")
3. search won't find it

### Expected behaviour

The search trims trailing spaces (if not specified somehow explicitly) and the finds the something (in eg. the folder "files")

### Actual behaviour

The folder "files" is not found, as it is searched for "files "

### Additional information

This behaviour frustrates me as searching often returns nothing where it shouldn't.

I haven't considered files/folders actually ending on a space, they don't make sense to me that much and should be found none the less.
