Subject [jira] Commented: (SOLR-1568) Implement Spatial Filter
Date Mon, 04 Jan 2010 19:03:55 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1568?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12796289#action_12796289
] 

Yonik Seeley commented on SOLR-1568:
------------------------------------

The examples are not of equivalent power.  What field are we working off of?  Are we filtering
by bounding box or by distance, sorting by distance, or boosting by distance?

Further, given that query parsers default to grabbing global params if local ones aren't specified
this
{code}
&fq={!sfilt p=49,-77 d=1000 f=location}
{code}

could be written as 
{code}
&fq={!sfilt f=location}
&p=49,-77
&d=1000
{code}

Which I assumed people would do anyway to make it easier for clients to construct queries
and do filtering + sorting w/o repeating parameters.

> 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}
