Apologies for any cross-posting.

OJAX federated search service software is now in Beta release and
available for download. Version 0.7 has improved performance, stability
and user feedback, as well as additional features such as RSS/Atom feed
support. (Atom feeds of stored searches alert users when new content
matching their interests is harvested.)

OJAX illustrates how federated search services can respond to new user
expectations generated by Web 2.0:

• Rich, dynamic user experience. OJAX uses Ajax technology to provide
immediate dynamic response to user input.

• Intuitive interface. The OJAX interface provides the simplicity and
familiarity of Google but with the power of advanced search
• Integration, interoperability and reuse. OJAX uses loosely coupled Web
Services and supports the OpenSearch RSS standard, thus facilitating
integration with a range of virtual library environments, institutional
repositories, course management systems and institutional portals.

• Open source standards-compliance. OJAX supports best-practice open
source standards and software, including OpenSearch, OAI-PMH, StAX and
Apache Lucene.

Features of OJAX:
* Auto-completion of search terms
* Triggering of auto-searches
* Dynamically scrollable search results - no more navigating between pages
* Auto-expansion of search result details
* Rapid sorting of results
* Integrated with the Firefox 2 / IE 7 search feature
* Supports OpenSearch Discovery
* Stored searches as Atom feeds
* Includes an OAI-PMH harvester
* Easy to install in your own institution
