David Smiley commented on SOLR-1568: ------------------------------------ I've finally tried this out successfully. But I needed a lat-lon box search, not a circle. It wasn't hard to modify the code to offer a lower-left point and upper-right point. I only implemented this for the Spatial Tiers point implementation. The odd part was that the code internally wanted to know the diameter of a circle based search in miles. So I translated this to the distance from one corner of the box search to the oppose one... then divided by the square root of 2 to reduce this amount to what the diameter would be of a circle fitting *within* the box search. I haven't bothered with any scoring modification, I'm most interested in filtering. > Implement Spatial Filter > ------------------------ > > Key: SOLR-1568 > URL: https://issues.apache.org/jira/browse/SOLR-1568 > Project: Solr > Issue Type: New Feature > Reporter: Grant Ingersoll > Assignee: Grant Ingersoll > Priority: Minor > Fix For: 1.5 > > Attachments: CartesianTierQParserPlugin.java, > SOLR-1568.Mattmann.031010.patch.txt, SOLR-1568.patch, SOLR-1568.patch, > SOLR-1568.patch, SOLR-1568.patch, SOLR-1568.patch, SOLR-1568.patch, > SOLR-1568.patch, SOLR-1568.patch > > > Given an index with spatial information (either as a geohash, > SpatialTileField (see SOLR-1586) or just two lat/lon pairs), we should be > able to pass in a filter query that takes in the field name, lat, lon and > distance and produces an appropriate Filter (i.e. one that is aware of the > underlying field type for use by Solr. > The interface _could_ look like: > {code} > &fq={!sfilt dist=20}location:49.32,-79.0 > {code} > or it could be: > {code} > &fq={!sfilt lat=49.32 lat=-79.0 f=location dist=20} > {code} > or: > {code} > &fq={!sfilt p=49.32,-79.0 f=location dist=20} > {code} > or: > {code} > &fq={!sfilt lat=49.32,-79.0 fl=lat,lon dist=20} > {code} -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
