Subject [jira] Commented: (SOLR-1568) Implement Spatial Filter
Date Mon, 04 Jan 2010 20:57:54 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1568?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12796352#action_12796352

Ryan McKinley commented on SOLR-1568:

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

Jeez -- I had no idea...  then I think (most?) cases are taken care of...

With this, a handler could be defined with the default param: 'fq={!sfilt f=location}' and
the 'end user' could simply call:
  &p=49,-77&d=1000
never needing to grock the local-params/function syntax.

> 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}
