| <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>. |

| <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. |

| <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> |

| 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 |

| <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. |

| <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. |
