基于LUCENE的通用检索框架

LIUS - Lucene Index Update and Search

http://www.bibl.ulaval.ca/lius/index.en.html

LIUS is an indexing Java framework based on the Jakarta Lucene project. The LIUS framework adds to Lucene many files format indexing fonctionalities as: Ms Word, Ms Excel, Ms PowerPoint, RTF, PDF, XML, HTML, TXT, Open Office suite and JavaBeans.

Indexing JavaBeans can be really useful when we want to index databases and more precisely when the user is programming the persistence layer (or the database connexion) while using ORM (Object Relational Mapping) like Hibernate, JDO, Torque, TopLink, etc.

LIUS also makes it possible to carry out a mixed indexing, (indexing) which the purpose is to integrate all the contents of a repertory (directory) under the same occurrence. This is very useful when the user want to index XML metadata, PDF plain text or in an other format. What makes it possible thereafter, for example, to carry out research on the title, author and the plain text at the same time.

LIUS is very easy to use; all the configuration of the indexing (types of files to be indexed, fields, etc...) as well as research is defined in a XML file, so the user only have to write few lines of code to carry out the indexing or research.

Compass Framework

The Compass Framework is a first class open source Java framework, enabling the power of Search Engine semantics to your application stack decoratively. Built on top of the amazing Lucene Search Engine, Compass integrates seamlessly to popular development frameworks like Hibernate and Spring. It provides search capability to your application data model and synchronises changes with the datasource. With Compass: write less code, find data quicker.

As of version 0.8, Compass also provides a Lucene Jdbc Directory implementation, allowing storing Lucene index within a database for both pure Lucene applications and Compass enabled applications. Note, when using Compass, using a database as the index storage requires only updating configuration settings.
