Apache Solr

Apache Solr is an open-source enterprise search platform written in Java from the Lucene project. Solr is a popular search platform for Web sites because it can search within PDFs and Word docs, as well as display recommendations for related content based on the search query’s taxonomy. Other features include faceted search, real-time indexing and database integration. We have used Solr on multiple projects such as the Lama Yeshe Wisdom Archive and Northeast Energy Efficiency Partnership.
