Many thanks for the response, but I'm afraid it's not quite what I meant. I should have been a bit more specific: if I do an advanced search, and look for "sword dragons" (without quotation marks) in the mod description at Skyrim Nexus, there are no hits. I believe this is because the search is done for the string "sword dragons" rather than containing "sword" AND "dragons". I am guessing that there is another way to search for any mod containing both "sword" and "dragons" in the description, e.g. "sword, dragons" or "sword; dragons", but so far no luck.
