<p>This package makes it possible to filter and sort according to

geographical constraints. For example, filter to include only

restaurants within 2 miles of a specified latitude/longitude, sorting
|

by distance ascending.</p>

for details on the technical approach.</p>

|

<p>Unfortunately, this package is still very new, and has little to no

documentation. It's best to ask for pointers on

java-user@lucene.apache.org, and look at the unit tests included in

the source distribution.</p>
