SOLR 3.4 GeoSpatial Query Returning distance

[Anand Henry <an...@gmail.com>]

Hi,

In SOLR 3.4, while doing a geo-spatial search, is there a way to retrieve
the distance of each document from the specified location?

I am aware of the workaround mentioned at
http://wiki.apache.org/solr/SpatialSearch/#Returning_the_distance, however
it doesn't work for me, since search terms also have to be included as part
of the query.

Thanks,
Anand

Hi,
I've not tested it by myself but I think that can take advantage of Solr
4's pseudo fields, by adding something like :

&fl=*,geodist(),score

I think you could even pass several geodist() calls with different
parameters if you want to have the distance wrt several POIs ^-^

SOLR 4 only.

Not that I know of.

What we did was to read and parse the location field on client side and 
calculate the distance on our own using this library:

http://code.google.com/p/simplelatlng/

However, it's not as "nice" as getting the distance from Solr, and 
sometimes the distances seem to slightly differ - e.g. when you filter 
up to a distance of 100 km, there are cases where the client library 
still computes 100.8 km or so.

But at least, it's working.
