=> Open question: how to do this without
compromising state/scalability?
+PROBLEM GROUP 7 (User experience):
+* Searches often do not return a sufficient / significant number of
+ results
+* Sharing a directory with thousands of similar files (image/jpeg)
+ creates thousands of search results for the mime-type keyword
+ (problem with DB performance, network transmission, caching,
+ end-user display, etc.)
+
+SOLUTION (draft, not done yet, details missing...):
+* Canonicalize keywords (see suggestion on mailinglist end of
+ June 2009: keep consonants and sort those alphabetically);
+ while I think we must have an option to disable this feature
+ (for more private sharing), I do think it would make a reasonable
+ default
+* When sharing directories, extract keywords first and then
+ push keywords that are common in all files up to the
+ directory level; when processing an AND-ed query and a directory
+ is found to match the result, do an inspection on the metadata
+ of the files in the directory to possibly produce further results
+ (requires downloading of the directory in the background)
