Otis,
Thanks a lot. I'd certainly follow your advice and check the logs. Although,
I must say that I've already tried all possible variations of the string for
the "fl" parameter (spaces, commas, plus signs). More than that - the query
still doesn't want to fetch any docs (other than the one with the id
specified in the query) even when the line solrQuery.setParam("fl", "title
author score"); is commented out. So I suspect that the problem is that the
request with the url
"http://localhost:8080/solr/select?q=id:1&mlt=true&mlt.fl=content&..."; due
to some reason doesn't work properly. And when I use the GetMethod(url)
approach and send url directly in the form
"http://localhost:8080/solr/mlt?q=id:1&mlt.fl=content&...";, Solr picks up
the mlt component. (At least, I'll have this backup solution if the main one
keeps committing sabotage. :) I'll just need to add a parser for an incoming
xml-response.)
I'll continue my "research" of this issue and, if you're interested in
results, I'll definitely let you know.
Cheers,
Sergey
