David Smiley resolved LUCENE-7719. ---------------------------------- Resolution: Fixed Fix Version/s: master (7.0) > UnifiedHighlighter doesn't handle some AutomatonQuery's with multi-byte chars > ----------------------------------------------------------------------------- > > Key: LUCENE-7719 > URL: https://issues.apache.org/jira/browse/LUCENE-7719 > Project: Lucene - Core > Issue Type: Bug > Components: modules/highlighter > Reporter: David Smiley > Assignee: David Smiley > Priority: Minor > Fix For: master (7.0) > > Attachments: LUCENE_7719.patch > > > In MultiTermHighlighting, a CharacterRunAutomaton is being created that takes > the result of AutomatonQuery.getAutomaton that in turn is byte oriented, not > character oriented. For ASCII terms, this is safe but it's not for > multi-byte characters. This is most likely going to rear it's head with a > WildcardQuery, but due to special casing in MultiTermHighlighting, > PrefixQuery isn't affected. Nonetheless it'd be nice to get a general fix in > so that MultiTermHighlighting can remove special cases for PrefixQuery and > TermRangeQuery (both subclass AutomatonQuery). > AFAICT, this bug was likely in the PostingsHighlighter since inception. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
