Uwe Schindler updated LUCENE-2064:
----------------------------------
Comment: was deleted
(was: This is cool.
Highlighter & MTQ is broken in 2.9.1 - why not put this into 3.0 it is not more
broken than highlighter at all, but it would prevent people from more broken in
3.0.
Thinking about this patch, but it should really make it into 3.0, because it
would help people, that migrated to 3.0, and highlighter would be broken more
without it.
+1 for 3.0)
> Highlighter should support all MultiFieldQuery subclasses without casts

> Project: Lucene - Java
> Issue Type: Improvement
> Components: contrib/highlighter
> Affects Versions: 2.9.1
> Reporter: Simon Willnauer
> Assignee: Simon Willnauer
> Fix For: 3.0

>
> In order to support MultiTermQuery subclasses the Highlighter component
> applies instanceof checks for concrete classes from the lucene core. This
> prevents classes like RegexQuery in contrib from being supported. Introducing
> dependencies on other contribs is not feasible just for being supported by
> the highlighter.
> While the instanceof checks and subsequent casts might hopefully go somehow
> away in the future but for supporting more multterm queries I have a
> alternative approach using a fake IndexReader that uses a RewriteMethod to
> force the MTQ to pass the field name to the given reader without doing any
> real work. It is easier to explain once you see the patch - I will upload
> shortly.
