Search for multiple tags

[JoeHardi]

Is your feature request related to a problem? Please describe.
No, it's not related to a problem.
When searching for an image or a tag all the results for the keyword or tag will then be displayed. But if I'd like to search for two tags, e.g. "Myself" and "Dad", I can always only look for one tag at once.

Describe the solution you'd like
To have the possibility to search for multiple tags. To see on which picture the two - or even three, four - of us are tagged.

Describe alternatives you've considered
None.
