Uwe Schindler commented on LUCENE-3907: --------------------------------------- bq. Back grams would work for leading wildcards. They might be useful for things where the head is at the end (tail-first?), like domain names. If you need reverse n-grams, you could always add a filter to do that afterwards. There is no need to have this as separate logic in *this* filter. We should split logic and keep filters as simple as possible. > Improve the Edge/NGramTokenizer/Filters > --------------------------------------- > > Key: LUCENE-3907 > URL: https://issues.apache.org/jira/browse/LUCENE-3907 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Michael McCandless > Assignee: Uwe Schindler > Labels: gsoc2012, lucene-gsoc-12 > Fix For: 4.2 > > > Our ngram tokenizers/filters could use some love.
