+ Geographical filtering & sorting with Lucene
+ </title>
+ </head>
+ <body>
+
+<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>
+
+<p>See <a href="http://www.nsshutdown.com/projects/lucene/whitepaper/locallucene_v2.html">here</a>
+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>
+
+<p>There are also known issues, eg at
+least <a href="https://issues.apache.org/jira/browse/LUCENE-1815">LUCENE-1781</a>
+and <a href="https://issues.apache.org/jira/browse/LUCENE-1815">LUCENE-1815</a>.</p>
+
+<p><font color="red"><b>NOTE:</b> This package is still in flux and
+might change in incompatible ways in the next release.</font>
