[jira] [Updated] (LUCENE-7717) UnifiedHighlighter doesn't highlight
PrefixQuery with multi-byte chars
[ https://issues.apache.org/jira/browse/LUCENE-7717?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
David Smiley updated LUCENE-7717:
---------------------------------
Affects Version/s: 5.1
Fix Version/s: 6.4.2
Summary: UnifiedHighlighter doesn't highlight PrefixQuery with multi-byte chars (was: UnifiedHighlighter don't work with russian PrefixQuery)
Closing. I'll create a linked follow-up bug issue for WildcardQuery (also applies to Regexp) where we can discuss how to deal with that -- the more overall fix. I don't think that one should hold up a 6.4.2. It'll likely result in removing the PrefixQuery and TermRangeQuery sections in MultiTermHighlighting.
