Location Based Searching – Long Lat?

[Spadez <ja...@hotmail.com>]

Hi,

If I want to do a proximity search and they have provided me with a name of
a city, for example, “London”. How do I search this by proximity within
Solr?

I am assuming I first need a process to convert the city name to a long and
lat, so that Solr can understand where London is. Is this something that I
need to build into my PHP application or is there a system for this already
in Solr? 

Secondly, how does it work with the size of the city. If I want to search
for pizza in London, how do I automatically put a radius of say 100 miles on
it, whereas if it is a small town the radius would only be small, say 20
miles.

Thanks for any help you can give,

James

Hi,

There is no geocoding API in Solr as per now so you could handle that in your PHP app.
But check out https://issues.apache.org/jira/browse/SOLR-2833 for potential solution. I have a first version of the processor which I can upload to that JIRA if you're interested.
