<h2 class="boxed">Lucene Sandbox</h2>
<div class="section">
<p>
Lucene project also contains a workspace, Lucene Sandbox, that is open to all Lucene committers, as well
as a few other developers. The purpose of the Sandbox is to host various third party contributions,
and to serve as a place to try out new ideas and prepare them for inclusion into the core Lucene
distribution.<br>
Users are free to experiment with the components developed in the Sandbox, but Sandbox components will
not necessarily be maintained, particularly in their current state.
</p>
<p>
You can access the Lucene Sandbox repository at
<a href="http://svn.apache.org/repos/asf/lucene/java/trunk/contrib/">http://svn.apache.org/repos/asf/lucene/java/trunk/contrib/</a>.
</p>
<a name="N10023"></a><a name="Snowball Stemmers for Lucene"></a>
<h3 class="boxed">Snowball Stemmers for Lucene</h3>
<p>
This project provides pre-compiled versions of the Snowball stemmers
for Lucene.
</p>
<p>
<a href="http://svn.apache.org/repos/asf/lucene/java/trunk/contrib/snowball">The
repository for the Snowball contribution.</a>
</p>
<p>
<a href="http://snowball.tartarus.org/">Background information on Snowball</a>,
which is a language for stemmers developed by Martin Porter.
</p>
<a name="N1003A"></a><a name="Analyzers, Tokenizers, Filters"></a>
<h3 class="boxed">Analyzers, Tokenizers, Filters</h3>
<p>
Contributed Analyzers, Tokenizers, and Filters for various languages.
</p>
<p>
<a href="http://svn.apache.org/repos/asf/lucene/java/trunk/contrib/analyzers/">The
repository for the Analyzers contribution.</a>
</p>
<a name="N1004A"></a><a name="Ant"></a>
<h3 class="boxed">Ant</h3>
<p>
The Ant project is a useful Ant task that creates a Lucene index out of an Ant fileset. It also
contains an example HTML parser that uses JTidy.
</p>
<p>
<a href="http://svn.apache.org/repos/asf/lucene/java/trunk/contrib/ant/">The
repository for the Ant contribution.</a>
</p>
<a name="N1005A"></a><a name="WordNet/Synonyms"></a>
<h3 class="boxed">WordNet/Synonyms</h3>
<p>
The Lucene WordNet code consists of a single class which parses a prolog file
from the WordNet site that contains a list of English words and synonyms.
The class builds a Lucene index from the synonyms file. Your querying code could
hit this index to build up a set of synonyms for the terms in the
search query.
</p>
<p>
More information on the <a href="http://www.tropo.com/techno/java/lucene/wordnet.html">Lucene WordNet package</a>.
<a href="http://wordnet.princeton.edu/">WordNet</a> is an online database of English language words that contains
synonyms, definitions, and various relationships between synonym sets.
</p>
<p>
<a href="http://svn.apache.org/repos/asf/lucene/java/trunk/contrib/wordnet/">The
repository for the WordNet module.</a>
</p>
<a name="N10075"></a><a name="Lucli - Lucene Command-line Interface"></a>
<h3 class="boxed">Lucli - Lucene Command-line Interface</h3>
<p>
The Lucli application allows index manipulation from the
command-line.
</p>
<p>
<a href="http://svn.apache.org/repos/asf/lucene/java/trunk/contrib/lucli/">The
repository for the Lucli contribution.</a>
</p>
<a name="N10085"></a><a name="Term Highlighter"></a>
<h3 class="boxed">Term Highlighter</h3>
<p>
A small set of classes for highlighting matching terms in
search results.
</p>
<a href="http://svn.apache.org/repos/asf/lucene/java/trunk/contrib/highlighter/">The
repository for the Highlighter contribution.</a><a name="N10092"></a><a name="Javascript Query Constructor"></a>
<h3 class="boxed">Javascript Query Constructor</h3>
<p>
Javascript library to support client-side query-building. Provides support for a user interface similar to
<a href="http://www.google.com.sg/advanced_search">Google's Advanced Search</a>.
</p>
<p>
<a href="http://svn.apache.org/repos/asf/lucene/java/trunk/contrib/javascript/queryConstructor/">The
repository for the Javascript Query Constructor files.</a>
</p>
<a name="N100A6"></a><a name="Javascript Query Validator"></a>
<h3 class="boxed">Javascript Query Validator</h3>
<p>
Javascript library to support client-side query validation. Lucene doesn't like malformed queries and tends to
throw ParseException, which are often difficult to interpret and pass on to the user. This library hopes to
alleviate that problem.
</p>
<p>
<a href="http://svn.apache.org/repos/asf/lucene/java/trunk/contrib/javascript/queryValidator/">The
repository for the Javascript Query Validator files.</a>
</p>
<a name="N100B6"></a><a name="High Frequency Terms"></a>
<h3 class="boxed">High Frequency Terms</h3>
<p>
The miscellaneous package is for classes that don't fit anywhere else. The only class in it right now determines
what terms occur the most inside a Lucene index. This could be useful for analyzing which terms may need to go
into a custom stop word list for better search results.

<h3 class="boxed">GData-Server</h3>
<p>
Apache - Lucene based serverside implementation of <a href="http://code.google.com/apis/gdata/">Google's GData</a> protocol. GData-Server provides an extendable
full featured gdata feed server to add, remove, update ATOM 1.0 and RSS 2.0 feeds.
Feeds are searchable via a defined HTTP GET parameter based query language like the Lucnene query syntax.
