Hi Vladimir, Yes, you are close. Solr doesn't use SOAP, though, and JSON is only one of its outputs. Solr can be described as a REST-ish web service. You trigger it via HTTP GET requests and responses are XML, or JSON, or something else in the future.
I think you are right about Compass, but I have not used it, so I'm not certain. All of these should really get some coverge in the upcoming Lucene in Action part deux.

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?
