Subject [jira] [Updated] (LUCENE-3238) SpanMultiTermQueryWrapper with Prefix Query issue
Date Fri, 24 Jun 2011 14:21:53 GMT

Hi, definitely a bug, thank you!

In my opinion, WildcardQuery should not try to override MultiTermQuery's rewrite here, it
causes too many problems.

Instead, in this case it should just return a PrefixTermEnum... this is the way we handle
these things in trunk and I think we should fix it here the same way.

> If we try to do a search with SpanQuery and a PrefixQuery this message is returned:
> "You can only use SpanMultiTermQueryWrapper with a suitable SpanRewriteMethod."
> The problem is in the WildcardQuery rewrite function.
> If the wildcard query is a prefix, a new prefix query is created, the rewrite method
is set with the SpanRewriteMethod and the prefix query is returned.
> But, that's the rewritten prefix query which should be returned:
> -      return rewritten;
> +      return rewritten.rewrite(reader);
> I will attach a patch with a unit test included.
