I > mean > per-term caching or something, internal to Lucene, or may be SOLR (SOLR > may > use own query parser)... > > Anyway, I implemented BK-Tree and playing with it right now, I altered > FuzzyTermEnum class of Lucene... > http://en.wikipedia.org/wiki/BK-tree > > - it seems performance of fuzzy searches boosted at least hundred times, > but > I need to do more tests... repeated similar (slightly different) queries > run > with better performance, probably because of OS-level file caching... > but it > could be that of BK-Tree distance! (although I need to use classic int > instead of float distance by Lucene/Levenstein etc.) > > Thanks, > Fuad Efendi > +1 416-993-2060 > http://www.tokenizer.ca/ > Data Mining, Vertical Search > > >
