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 released but thanks for your help!

>                 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
