I'm somewhat new to Solr (it's running, I've been through the books, but I'm no master). What I hear you say is that MLT *can* accept, say 5, documents and provide results, but the results would essentially be the same as running the query 5 times for each document?
If that's the case, I might accept it. I would just have to merge them together at the end (perhaps I'd take the top 2 of each result, for example). Being somewhat new I'm a little confused by the difference between a "Search Component" and a "Handler". I've got the /mlt handler working and I'm using that. But how's that different from a "Search Component"? Is that referring to the default /solr/select?q="..." style query? And if what I said about multiple documents above is correct, what's the syntax to try that out? Thanks very much for the great help!

MLT has both a request handler and a search component. The MLT handler returns similar documents only for the first document that the query matches. The MLT search component returns similar documents for each of the documents in the search results, but processes each search result base document one at a time and keeps its similar documents segregated by each of the base documents. It sounds like you wanted to merge the base search results and then find documents similar to that merged super-document. Is that what you were really seeking, as opposed to what the MLT component does? Unfortunately, you can't do that with the components as they are. You would have to manually merge the values from the base documents and then you could POST that text back to the MLT handler and find similar documents using the posted text rather than a query. Kind of messy, but in theory that should work. -- Jack Krupansky -----Original Message----- From: David Parks Sent: Tuesday, December 25, 2012 5:04 AM To: solr-user@lucene.apache.org Subject: MoreLikeThis supporting multiple document IDs as input? I'm unclear on this point from the documentation. Is it possible to give Solr X # of document IDs and tell it that I want documents similar to those X documents? Example: - The user is browsing 5 different articles - I send Solr the IDs of these 5 articles so I can present the user other similar articles I see this example for sending it 1 document ID: http://localhost:8080/solr/select/?qt=mlt&q=id:[document id]&mlt.fl=[field1],[field2],[field3]&fl=id&rows=10 But can I send it 2+ document IDs as the query?
