Yonik Seeley commented on SOLR-773:
-----------------------------------
It seems like quite a lot of work has gone into working around some of Solr's
current limitations... perhaps we should fix them instead? It seems like we
should be able to avoid custom request handlers, query components, or update
processors and simply use generic mechanisms.
>From the user interface point of view, what's needed is:
- A way to filter by a bounding box. This could simply be a custom QParser
fq={!gbox p=101.2,234.5 f=position, d=1.5}
// a bounding box, centered on 101.2,234.5 including everything within 1.5 miles
- A function query that calculates distances
gdist(position,101.2,234.3)
- A way to sort by a function query... this is generic desired functionality
anyway!
- A way to return the value of a function query for documents - also generic
desired functionality. Perhaps use meta as proposed in SOLR-705?
If we had that, then geo becomes very generic - no need for special distributed
search support, and one could do things like boosting the relevancy score by a
function of the distance (not even necessarily a linear boost because of the
flexibility of function query). If/when we get faceting on a function query, it
will also automatically work with distances.
It seems like points should be stored and represented in a single field, that
way there can be multiple points per document (otherwise how would one
correlate which latitude went with which longitude). How it's indexed (multiple
fields, etc) is more of an implementation detail. There is an issue with *how*
to allow a single field to index to multiple fields - another Solr limitation
we should figure out how to fix (an earlier version of TrieRangeQuery needed
this too).
