IBM and Yahoo have announced a free enterprise search software. Called IBM OmniFind Yahoo! Edition, it neither uses IBM's nor Yahoo's technology for underlying search but instead runs on Lucene, an open source search technology from Apache. Since Lucene is already popular option for implementing search for many J2EE implementations, this could present a good option as it should be easier to integrate and extend it without learning new proprietary search APIs. This promises a good entry level solution that is easy to setup and configure -- qualities generally not associated with search products. So it'll be interesting to see how other search vendors respond. Yahoo's contribution is its familiar search interface -- yet another example of how consumer web technologies are making inroads into the enterprise.
