I'm not sure why you'd want to do this when you can just pass the
query string to the search_each method and it does it for you. What
exactly are you trying to do? Can't you just do this;
query = Search::TermQuery.new(:name, "Joe".downcase)
Anything more complicated than this and you are better off leaving it
to the QueryParser.
Cheers,
Dave
