Robert Muir commented on LUCENE-5620: ------------------------------------- but doing this selectively (only adding additional terms in some cases) is pretty complicated if you dont want to screw over length normalization. So it probably hurts more than it helps really. As for english language: its irrelevant here. > LowerCaseFilter.preserveOriginal > -------------------------------- > > Key: LUCENE-5620 > URL: https://issues.apache.org/jira/browse/LUCENE-5620 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Mike Sokolov > Attachments: LUCENE-5620.patch > > > Following closely the model of LUCENE-5437 (which worked on > ASCIIFoldingFilter), this patch adds the ability to preserve the original > token to LowerCaseFilter. This is useful if you want an all-lowercase search > term to match without regard to case, while search terms with uppercase > letters match in a case-sensitive manner. -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
