Hello -
article <http://www.gissearch.com/location_extraction_solr> Background:
(on solr 1.3)
We're doing a similar thing with our location data - however we're
finding that if the 'input' string is one long string i.e.: q=
*Philadelphia,PA,19103,US*
that we're getting *0* matches -
Instead of relying on the application to convert the input query to : q=
*Philadelphia, PA, 19103, US* (which does work), we're hoping that there
could be something we could apply something to the q parameter make it
treat the commas as spaces and execute the search.
Here are the 2 results from the search:

tandard&version=2.2&rows=10} hits=*174736* status=0 QTime=406
And the second query's debug output:
