Subject [jira] Commented: (SOLR-1568) Implement Cartesian Tier Filter
Date Wed, 18 Nov 2009 21:02:39 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1568?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12779662#action_12779662

Grant Ingersoll commented on SOLR-1568:
---------------------------------------

Honestly, it's a bit tricky and I'm not sure how best to resolve it (keep in mind that I'm
not recommending the above piece be committed).  There are a few pieces that can be improved
in the CartesianShapeFilter to perform better (I still need to fix them in Lucene) but if
I go that route, then I need to update the Lucene JARs associated with that in Solr.  I can't
really do that, b/c that likely means one of two things:

1. Patching the 2.9.1 branch and packaging up that JAR for Solr or wait for a 2.9.2 release
from Lucene which isn't likely.
2. Patching trunk and including it.  This would be a huge undertaking for Solr

So, in the end, my decision was based on the fact that the code for it was pretty simple and
wouldn't be a big deal to fix.  Longer term, I will fix the issue in trunk of Lucene and then
over time Solr can adapt to use that once we are on 3.x

> Given an index with cartesian tiers, we should be able to pass in a filter query that
takes in the field name, lat, lon and radius and produces an appropriate Filter for use by
Solr.  Note, contrib/spatial has such a filter, so it may just be that we need to hook in
a QParserPlugin to handle it.
