Here is a patch to add spacial search to haystack with Solr backend:
http://1cafe.fr/spacial.diff.txt

Patch is build on django-haystack-1.0.1-final.tar.gz.

This patch works with the jteam spacial plugin for Solr:
http://www.jteam.nl/news/spatialsolr

Here is an exemple of a spacial search, for instance searching all the
result within 3km from a center point:
SearchQuerySet().spacial(lat=49.4338870, long=1.0888390, radius=3,
unit='km').order_by('-geo_distance')

Of course this patch is a quick and dirty fix for people who wants to
run spacial queries with haystack. It works well for me, so may be it
will for others.

and spatial queries should be done like this:

SearchQuerySet().spatial(lat=49.4338870, long=1.0888390, radius=3,
unit='km').order_by('-geo_distance')

Here're some notes attached to it:

Hi

this is great for everybody,as this solr extension is used by many people
already, why don't you submit it to the main repository ?

- Firstly, i want to implement the changes for Solr 1.3+ . Since solr now
has built in support for Geo stuff, i think that should be natively
supported by haystack now.
I'll send a pull request, after i've done that. Someone else(Samuel Joos)
did send me some changes he did to make it work, which i'll try to commit to
github.

As far as the JTeam SSP is concerned
- Also, I don't think support for an extra plugin like belongs in the main
repository.

- The current code base is haystack 1.1.1 i think, so need to merge in the
latest master and test it out.
-  The plugin jar i used was 1.x, but JTeam seems to have upgraded it to 2.x
so will have to see if there are backward compatible changes.

Thanks for this explanation Siddartha
I did not check Solr for a while and did not know they had their own geo
support shipping now, good news

I have made port of your patch for solr 3.4 and haystack 2.* and looks
like it works :-)

You can find all stuff on github https://github.com/frutik/django-haystack

Usage example:

from haystack.query import SearchQuerySet
s = SearchQuerySet()
s.spatial(lat=9.671519, long=46.686754000000001, sfield='location',
distance=10)

Hopefully it can be usefull for somebody else

Kind regards,
Andrew

Hi Andrew,

     Can you link to the specific commit with your changes. I only see the
Readme change on your repo. I didn't see any branches with spatial related
commits. Maybe i'm missing something.

Anyways i'd been experimenting with Solr 3.4 + haystack. I just pushed
whatever changes i had last to a separate branch for now "solr34"
https://github.com/sidmitra/django-haystack-spatialsolrplugin/tree/so...

It's not working yet, but i was trying to use the solr built in LatLon
field type. Will work when i'm free next(tricky!). Feel free to share your
code. It'll be a great help seeing your implementation.

I've been thinking of merging my JTeam SSP + this solr34 work into the same
branch. Maybe add a flag to settings.py to figure out what query syntax to
use. They're pretty similar.
Although SSP 2.x, differs from SSP 1.x, so i'd have to maintain 3 syntaxes
slightly different in their own ways. But should be simple enough. Maybe in
the future i can look at geohash etc. as well.
