Hello, I want to build a RDF-based search engine and I want to use for this purpose at the first stage Lucene, Solr and SIREn. I assume I need also an inverted index etc.
Am I right? I look to forward to every hint.
P.S.: May be I need (also) Nutch? Whatever I don't know at the moment which one (Nutch/Solr) is the best one for RDF-based Web search....
