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.

Lucene can be run as a service inside <a href="http://jakarta.apache.org/turbine/fulcrum/index.html">Fulcrum</a>,
|
|
|
|
|
which is the services framework from the
|
|
|
|
|
<a href="http://jakarta.apache.org/turbine/">Turbine</a> project.</p>
|
|
|
|
|
<p>
|
|
|
|
|
The implementation consists of a SearchService interface, a LuceneSearchSearchService implementation, and a
|
|
|
|
|
SearchResults object that gets an array of Document objects from a Hits object. Calls to the search methods on
|
|
|
|
|
the service return the SearchResults object.

|
|
|
|
|
<p>

2003-01-31 14:42:30 -05:00

The service supports querying, but does not support indexing.

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>

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.

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.
