### Problem Description

Applying search filters is a bit unconvienent, as I have to:

1. click on the funnel icon
2. set the search filters
3. close the search filters modal
4. click on the magnifier icon to trigger a search

To speed up things, step three can be eliminated.

### Proposed Solution

How? add a new "Search"-button next to the "Close"-button in the search filters modal that immediately triggers a search with the search query and the selected filters:
