Support official Solr 3 spatial search APIs

There is some work done for integration of Search API with Solr 3.x here http://drupal.org/sandbox/mollux/1269950

I hope to merge that sandbox into this module and continue development for Solr 3.x.

I am currently working on a patch that will do this, expanding on mollux's work.

@ygerasimov, do you have a problem with removing the dependency on the location module? My thought is that is could use any module/field that provides lat/lng data, such as geofield.

Also, should I post patches here, or start a new ticket?

@wesnick I don't see any problem to remove dependency on location module. Only thing that should be done is to index geofield properly.

You are welcome to add patch here.

Here is a patch with some initial ideas. Requires patching of search_api_solr module as well as search_api_location. Please let me know if you think this is a good direction or if you have other implementation ideas.

Whoops, forgot to add in the the parameter merge in solr search.

EDIT: Also worth mentioning that for this to work, a field or module must define a suitable property. Geofield has this property, and in general it can be added to any entity/field using something like this in property_info callback.

'latlng' => array(
  'type' => 'text',
  'description' => 'Lat/Lng Datatype
  'getter callback' => 'my_latlng_getter'
)

With a corresponding getter

function my_latlng_getter($args) {
  return $args['lat'] . ',' . $args['lng'];
}

@ygerasimov and @wesnick, I will commit my code as soon as possible. Then we can merge the whole thing :)

I am very interested in this and will be testing the patches.

I am working on a project with Search API, Solr and Geofield, so I can test the patches in that context. After spending several days digging into Geospatial search with Solr and Geofield, I like the direction of the patches from wesnick.

code is cleaned up :) when I'm home tonight, I will push to my sandbox, and then we can start the merging.

@morningtime: If Location kan output a latlon field, then there is no problem :)
i'm also a fan of openlayers :) I think the best solution is to let the user choose if he wants a gmap map (current implementation) or select an openlayers map for picking the point and showing the results.
I have the code for both :)

Hi,

I put some work into this, and have it basically working on views and search_api_pages. I have commented (temporarily) the location module integration stuff since in its current state location doesn't integrate well with Entity API-- is it a field, an entity? And it seems they are moving towards a pure field implementation, but not there yet, so I have only worked with:

Geofield
Geolocation
Simplegeo

To work with geolocation I have added a patch for that module #1366642: Property Info callback for Entity API.

I have also made an input widget with a gmap, implemented natively, following the patterns of geolocation field and mollux's work on search_api_spatial sandbox.

This will work with search api pages and with search api views, though not all the options that appear have been fully implemented.

@morningtime: you can only query one spatial index per query. You can do multiple points against the same index, but as far as I know you can't search against multiple spatial fields in a single query.

Please give some feedback.

Simplegeo

Why not use Geocode? Did you not want to get stuck with Google?

Is there any estimation about a prerelease date?
Before or after this Christmas?

@larjon: it will be before Christmas :) I'm almost finished with the renaming process, and the the 7.x-2.x branch of this module will contain the code of http://drupal.org/sandbox/mollux/1269950

Looking forward to it!

I committed the renamed version of the search_api_spatial module to the 7.x-2.x branch.
So we have full support for the spatial search possibilities of Solr.

I have some free evenings the next weeks, so I will be working on the module.
feel free to test it :)
