Analyzer of Question Answering

This analyzer shows to what extent a search engine is able to answer queries asked in question format. These may include questions proper containing a question word ([what order is the aardvark in] [where is Lhasa located]) as well as other queries that imply a short and mostly uniform answer ([currency of Brasil] [nitric acid formula]).
The user's intent in such cases is to find such an answer. The higher its position in the search results, the better for the user. Ideally, it would appear in the first snippet or even higher, in the special result box.
