Re: Geographical distance searching

[patrick o'leary]

Might want to remove the *'s around that url http://www.nsshutdown.com/projects/lucene/whitepaper/locallucene.htm There's actually a download-able demo http://www.nsshutdown.com/solr-example_s1.3_ls0.2.tgz start it up as you would a normal solr example $ cd solr-example/apache-solr*/example $ java -jar start.jar Open up firefox (sorry demo ui was quick and dirty so firefox only) and go to http://localhost:8983/localcinema/ Make sure you specify localhost, there's a google maps key based upon the url's domain, and click 'Go' at the bottom of the page. The demo comes with some sample data already indexed for the NY region, so have a play. p.s after a little tidy up I'll be adding this to both lucene and solr's repositories if folks feel that it's a useful addition.

MySQL has a geographical database option, so maybe that is a better option than Lucene indexing.

I have indexed the lat and long info for each record in solr and also i can get the lat and long of the location input by the user. Previously we were using lucene to do this. by using the SortComparatorSource we could sort the documents returned by distance nicely. we are now switching over to lucene because of the features it provides, however i am not able to see a way to do this in Solr. If someone can point me in the right direction i would be very grateful! Thanks in advance, Sandeep     This email is confidential and may also be privileged.
