CMS Watch says 40 percent of WCM vendors are embedding Lucene for search: Interesting that vendors are settling around an open-source standard for search.
A new CMS Watch report, The Web CMS Report 2009, has found that many web content management vendors are embedding their own search tools into the CMS, and nearly 40 percent have chosen the open source search tool Lucene, a project from the Apache Foundation that has proven to be very popular.
eZ did this with eZ Find. It’s based on Solr, which is a server based around Lucene. It works beautifully. Incredibly configurable.
