[jira] Issue Comment Edited: (LUCENE-1731) Allow ConstantScoreQuery
to use custom rewrite method if using for highlighting
[ https://issues.apache.org/jira/browse/LUCENE-1731?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12729557#action_12729557 ]

Hi Mark,
Yeah i was aware the of the addition made but am i correct in saying this is only supported by the Solr highlighter (i.e. the "usePhraseHighlighting" params, etc)? ... Maybe i'm missing the point but i couldn't get any queries based on a TermsFilter to work with the lucene highlighter
-- Forget that, i've looked at the patches and i see how the improvement has been made. I'll just use my work around until lucene 2.9 is release but thanks for your help!

>
> Key: LUCENE-1731
> URL: https://issues.apache.org/jira/browse/LUCENE-1731
> Project: Lucene - Java
> Issue Type: Improvement
> Components: contrib/highlighter
> Affects Versions: 2.4, 2.4.1
> Reporter: Ashley Sole
> Priority: Minor
>
> I'd like to submit a patch for ConstantScoreQuery which simply contains a setter method to state whether it is being used for highlighting or not.
> If it is being used for highlighting, then the rewrite method can take each of the terms in the filter and create a BooleanQuery to return (if the number of terms in the filter are less than 1024), otherwise it simply uses the old rewrite method.
> This allows you to highlight upto 1024 terms when using a ConstantScoreQuery, which since it is a filter, will currently not be highlighted.
> The idea for this came from Mark Millers article "Bringing the Highlighter back to Wildcard Queries in Solr 1.4", I would just like to make it available in core lucene
