Geocoding with Solr
Hi!
I am using Solr as my main search system for my site. Currently, I am using
google to turn a place name (such as a postcode or city) into a long / lat
co-ordinate. Then I am supplying this long / lat to Solr so it can perform a
spacial search.
I am really new to this, but I dont like my reliance on google for this. Is
it possible to import a database into Solr which linked both cities and
postcodes to a co-ordinate, and use Solr for this as well?

Hi there,
You may want to check out:

SOLR-2081 BaseResponseWriter isStreamingDocs causes SingleResponseWriter.end
to be called 2x
SOLR-2082 Geopost.jar for loading geonames data
My student and I submitted those issues a few years ago
to handle geocoding in Solr and I think it's still a pretty useful
approach.
Cheers,
Chris

If I wanted to return long/lat from either "town" "city" or "postcode", how
would I structure it?
If I was just searching for towns it would be easy, like this:
> *Town, City, Postcode, Country, Long/Lat*
> Orpington, Kent, Uk, 1.2/1.1

However, but there will be "city" entries and "postcode", I dont how that
would work, would the entry just be for a city for example:

Spadez,
I've had some success into using the nicely open data of GeoNames.org but that was modestly only to fetch zip-code-to-town-name and long-lat associations, search for "postal-codes".
It would be lovely that some more best practice examples are distributed on how to handle, e.g., the lon-lat uncertainty.
I still do not know how I could take usefully advantage of a user-allowed-browser-geolocation which gives me lon/lat. I've seen article on how to do this with a YUI query thus far.
