Allow ConstantScoreQuery to use custom rewrite method if using for highlighting
-------------------------------------------------------------------------------
Key: LUCENE-1731
URL: https://issues.apache.org/jira/browse/LUCENE-1731
Project: Lucene - Java
Issue Type: Improvement
Components: contrib/highlighter
Affects Versions: 2.4.1, 2.4
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
