Hi, Couple of people mentioned here SOLR as a 'new' Lucene based search server. But NUTCH is also Lucene based. Also, there is an OpenSymphony initiative called 'Compass', which is rather an integration framework than server.
I wonder if anyone can come up with a small summary of what are scopes of each of the products above? I did some reading and shuffling, but not sure if I got it completely right. Here is my summary. Please, correct/add-in: - Lucene: the core/kernel of all the products. Contains all the search logic as well as index maintenance. - Nutch: Interent/Itranet search engine. Shipped with a web crawler and a framework to run the Nutch in clustered environment (Hadoop). Open Source 'Google' :). - Solr: SOAP/XML/JSON interface to the Lucene - Compass: a integration framework which wires your application with Lucene using Spring/Hibernate Am I close? Vlad
