Conflict between keyword specificity and empty query results

[Disastergirl]

There is a conflict using more poetic words detected that are in the Synesketch lexicon, however are too abstract for Chromatik tags so we end up with no results.

Please implement a compromise issue queries with one or more keywords by default and in the case of empty results, lower the keyword count and try again.
