Thanks for your valuable suggestion. My XML file does not contain <add> <doc> tags at all. Its just of this format <row id="1" lat="43.7895" lng="-73.1289" body=".....Some text...."> </row> According to me(if my understanding is right), <add><doc> posts each record into a Solr document. This could be done, if I would be using only data consisting of lat,lng and body. But I need to generate 3 extra fields namely, geohash, lat_radians, lng_radians. I read somewhere that, these fields should have their respective values before indexing. The OSMhandler file has something called "geohash utils." This will take care of generating the appropriate geohash values. The function to_rads converts the given lat and lng values to radians. These were made use of in the examples that I had downloaded. They also made use of the OSM files for indexing. It was found that, files ending with any other extension was not taken for indexing at all. Thats why the file was renamed as .OSM though it was just a .XML file. The schema.xml and Solrconfig.xml have been changed to match my requirements. Now the problem is if I use a plain XML file, I should have pre-calculated values for geohash, lat_radians and lng_radians. How do I get these values? Can you please guide me, how to go about it, now that I've given more details?
