Hmmm, I don't see any screen shots. Several things: 1> If your stopword file has comments, I'm not sure what the effect would be. 2> Something's not right here, or I'm being fooled again. Your withresults xml has this line: <str name="parsedquery">+DisjunctionMaxQuery((meta_text:"ecol d ingenieur")~0.01) ()</str> and your noresults has this line: <str name="parsedquery">+DisjunctionMaxQuery((meta_text:"academi charpenti")~0.01) DisjunctionMaxQuery((meta_text:"academi charpenti"~100)~0.01)</str>
the empty () in the first one often means you're NOT going to your configured dismax parser in solrconfig.xml. Yet that doesn't square with your custom qt, so I'm puzzled. Could we see your raw query string on the way in? It's almost as if you defined qt in one and defType in the other, which are not equivalent. 3> It may take 12 hours to index, but you could experiment with a smaller subset. You say you know that the noresults one should return documents, what proof do you have? If there's a single document that you know should match this, just index it and a few others and you should be able to make many runs until you get to the bottom of this... And obviously your stemming is happening on the query, are you sure it's happening at index time too?
