Ishan Chattopadhyaya updated SOLR-1578:
---------------------------------------
Attachment: Indexer.java
solrconfig.xml
schema.xml
geocodercomponent_initial.patch
Here's an early patch based on the approach discussed in the talk. This is for
a geocoding component organized as a SearchComponent.
It uses per-field, in-memory bloom filters to perform quick query
classification into various hierarchical toponyms in the index. It takes in a
set of valid geocoding grammar rules (from solrconfig.xml) and for those
permutations of classifications that pass the grammar rules, it creates boolean
queries and fires against the index.
I have included a util class Indexer.java to index GeoNames US data into the
index.
The patch needs further work to handle queries containing house numbers etc.
Some queries that work:
http://HOSTNAME:8983/solr/collection1/geocoder?q=pizza%20near%20san%20francisco,%20ca
http://HOSTNAME:8983/solr/collection1/geocoder?q=california
http://HOSTNAME:8983/solr/collection1/geocoder?q=redwood+city
(Please replace HOSTNAME with geocoder.in for a live demo)
[[email protected]], [~dsmiley] and others, please review. Thanks.

> Given all the work around spatial, it would be beneficial if Solr had a query
> parser for dealing with spatial queries. For starters, something that used
> geonames data or maybe even Google Maps API would be really useful. Longer
> term, a spatial grammar that can robustly handle all the vagaries of
> addresses, etc. would be really cool.
