[jira] Commented: (SOLR-1568) Implement Spatial Filter

["Grant Ingersoll (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-1568?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12796249#action_12796249 ] 

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

Here's the thing I keep coming back to with this issue.  For all the field types other than SpatialTile (Cartesian Tier), filters are already easily creatable.  It seems odd to have to write this special QParserPlugin that has all this syntax support, etc. to create filters for all of the other cases beside the spatial tile.  For instance, pure radial distance filtering is easily handled through the FunctionRangeQParserPlugin and the various distance functions.  In fact, going this route is more convoluted for those cases b/c now you need a way to pass in what distance function you want to use.

> 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}
