Martijn van Groningen updated LUCENE-3602:
------------------------------------------
Attachment: LUCENE-3602.patch
Attached a new patch. Changes:
* Everything happens now in two passes.
* The second pass is in the custom MTQ impl.
* JoinUtil contains one method that returns a MTQ impl.
* Reused the tests from previous patch for the JoinUtil.
bq. But they can always choose the rewriteMode to not be AUTO and explicitly
choose filter if they want this.
Yes makes sense. First time I used the MTQ directly. So feedback on my on MTQ
impl is welcome :)
I think that this patch can easily be backported to 3x.
