Often times the technologies are so superb and crowd sourced so well that it is surprising that many people do not consider it as a valid strategy for their laboratories or companies. Take the example of Lucene.
Apache Lucene(TM) is a high-performance, full-featured text search engine library written entirely in Java. It is a technology suitable for nearly any application that requires full-text search, especially cross-platform. Apache Lucene is an open source project available for free download.
