# First, try to get question body with default filter
μ> (fmap head . askSE $ questionsOnUsers [972985] <> site "stackoverflow" ) >>= (^! field "body") :: IO String
*** Exception: user error (key "body" not present)

# Okay, create appropriate filter for this task and get its name
μ> (askSE $ createFilter ["question.body"] [] "default") >>= (^! field "items" . fields "filter") :: IO [String]
["!9hnGssGO4"]

# See
