[TYPO3-dam] search for strings in dam_frontend

[Jo]

Hello everyone,

I tried to use the search form in dam_frontend to find more than one
term which seems not to work. I only get results when searching for one
single searchword:

Example:
Search for "searchword1" shows results
Search for "searchword1 searchword2" shows no results but should list at
least results for searchword1

Is there a possibility to use the search form with multiple searchwords?

thx
Jo
