On my MW 1.14 (without Lucene) the search now results only crap when you include words with 4 or less letters. in 1.1q3 all was fine. Exampes:
Searching "the word" will return only talk pages when "word is found".
Searching "the" will find "the" (since when are 3 letter words indexed?) and result a few articles but mostly talk pages again.
Maybe there is more critical stuff I just didn't find yet.
