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.

SearchBean is a UI component that can be used to browse through the results of a Lucene search.
|
|
|
|
|
The SearchBean searches the index for a given query string, retrieves the hits, and then brings
|
|
|
|
|
them into the HitsIterator class, which can be used for paging and sorting through search results.

<subsection name="WordNet/Synonyms">
|

<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.

This contribution is some sample code that demonstrates adding simple XML documents into the index. It creates

a new Document object for each file, and then populates the Document with a Field for each XML element, recursively.
|
|

There are examples included for both SAX and DOM.

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.

into a custom stop word list for better search results.
