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>
|

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>

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.

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.
