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.

+ +

See here +for details on the technical approach.

+ +

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.

+ +

There are also known issues, eg at +least LUCENE-1781 +and LUCENE-1815.

+ +

NOTE: This package is still in flux and +might change in incompatible ways in the next release. + + + +
