Grant Ingersoll commented on SOLR-773:
--------------------------------------
Hi Bill (and everyone else),
I'm working on bits and pieces of this, as are others. I don't think there
will be one monolithic patch called "Local Solr" at this point as the donated
LocalSolr solves one particular spatial problem in one particular way. I
already added in distance function queries (see SOLR-1302) and am now working
on a QParserPlugin that will produce CartesianTier filters, possibly reusing
what is in contrib/spatial from Lucene, although I am not totally sold on what
is in their just yet either, implementation wise. It may require some cleanup
as well to be more generic and use newer Lucene capabilities. Basically, I am
executing on what Yonik, Ryan and I laid out around
https://issues.apache.org/jira/browse/SOLR-773?focusedCommentId=12733900&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_12733900,
https://issues.apache.org/jira/browse/SOLR-773?focusedCommentId=12703259&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_12703259
and
https://issues.apache.org/jira/browse/SOLR-773?focusedCommentId=12631963&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_12631963.
This result should be a much better Solr system overall, with the side effect
being we can now support spatial search.
As it stands now, I've been doing searches w/ filtering using the dist() and
hsin() methods in conjunction with Solr's frange functionality (see
http://www.lucidimagination.com/blog/2009/07/06/ranges-over-functions-in-solr-14/)
and that seems to be working quite well.
Other than that, I think the pieces that make up what is needed for spatial
search are now being tracked through the various dependent JIRA issues listed
above. I am going to keep this issue open as a way of tracking all the bits
and pieces that go into making Solr do spatial work. Once I feel they are
ready, then I will update here.
