Ahmet Arslan commented on LUCENE-4817: -------------------------------------- One other benefit of this filter is : it eliminates the confusion caused by wildcard searches on a stemmed field. Example : http://search-lucene.com/m/oOv5h2ZqC7Q1 > Add KeywordRepeaterFilter to emit tokens twice once as keyword and once not > as keyword > -------------------------------------------------------------------------------------- > > Key: LUCENE-4817 > URL: https://issues.apache.org/jira/browse/LUCENE-4817 > Project: Lucene - Core > Issue Type: Improvement > Components: modules/analysis > Affects Versions: 4.1 > Reporter: Simon Willnauer > Priority: Minor > Fix For: 5.0, 4.3 > > Attachments: docs.patch, LUCENE-4817.patch, LUCENE-4817.patch > > > if you want to have a stemmed and an unstemmed version of a token one for > recall and one for precision you have to do two fields today in most of the > cases. Yet, most of the stemmers respect the keyword attribute so we could > add a token filter that emits the same token twice once as keyword and once > plain. Folks would most likely need to combine this > RemoveDuplicatesTokenFilter but that way we can have stemmed and unstemmed > version in the same field. -- This message is automatically generated by JIRA.
