I would like to retrieve only those documents whose latitude and longitude fall inside a bounding box that has two co-ordinates, (x_1, y_1) and (x_2, y_2). Is there any way, I can implement this in lucene? Is it possible to extend the parser to understand a new syntax where I can express this in the text query and have the parser build a query that will contain all the logic necessary to do this check. Something like IN_BOX(latitude, longitude, 23.00, 26.00, 50.00, 60.00). Here latitude and longitude are two stored fields and 23,26 and 50,60 are the two co-ordinates for bounding box. I also checked the spatial package of lucene, but couldn’t find any pointers. Thanks, Prasad.
