Michael McCandless commented on LUCENE-1424:
--------------------------------------------

Excellent!

Looks like PrefixGenerator got lost.  Why not have it just get its bits by 
creating a PrefixQuery and calling getFilter().getDocIdSet()?

WildcardFilter is still in the patch.

Maybe fix getDocIdSet to not call bits() (since that's 2-pass, it's slower).  
In fact, does that Filter even need to implement bits?  Can we throw a not 
implemented exception, since it's a new Filter?

> If we want to be able to highlight these queries, they need to be added to 
> Lucene core or contrib (solr's WildCardFilter can be used to create the 
> ConstantScoreWildcardQuery). They are very useful anyway.
