Just carry an index on all the trigrams (sets of
contigious three
letters). No problem! :)
haha, yeah, thats how some fuzzy search methods work. Have you tried
performance of such an index - would be interesting to find out it
could be viable solution :)
of course, it would be better to put 'png' and 'jpg' into stopwords
(ergh, or strip file extensions entirely).
