Open Source Search Engines in Java

LIUS - Lucene Index Update and Search 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. 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. LIUS has been developed from a range of Java technologies and full open source applications.
