Subject [jira] Commented: (SOLR-1568) Implement Spatial Filter
Date Wed, 23 Jun 2010 15:09:56 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1568?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12881713#action_12881713

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

RE: multivalued.

Yes, this isn't necessarily a spatial issue.   Best solution would be a position based query
that took into account a specific position kind of like SpanFirstQuery.

Also, the distance parameter for points. How is it to be used for bounding box, where the
distance varies? In that case, calculating distance across the extent of the box is a waste
of cpu - a different calculation is needed for that - and a joined ranged could work.

I have a proposal to fix this if its needed.

Sure, it would be useful to have a proposal for this.  Hasn't been my focus for now, but open
to suggestions.

> 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}
