In less than 5 years, the landscape of enterprise search has been folded, spindled, and mutilated. The independent search solutions that are available are not yet household names among the Fortune 1000. They are, however, highly global. What is pushing aside the aging professionals is a rookie, an upstart -- Lucene/Solr. Lucene is the "library," or the plumbing, and Solr is the packaged solution. Lucene/Solr is available as free and open source software. There are some license restrictions, but for most organizations, Lucene/Solr is available without charge. In terms of features, Lucene/Solr is comparable to the Big Five enterprise search solutions. More important, Lucene/Solr is cloud-capable, outfitted with connectors to hook into Big Data management systems such as Hadoop, and equipped with the bells and whistles needed to scale across servers without too much manual fiddling. Paul Doscher, president and CEO of LucidWorks, one of the leading commercial open source search vendors, said that they have seen downloads of Lucene/Solr in the six figures this year. Interest is quite strong.
