'don't think so' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'soaks in town getting drunk with rafa?' is the wordplay.
'getting drunk with' indicates an anagram.
'soaks'+'in'+'town'='soaksintown'
'soaksintown' anagrammed with 'rafa' can make 'NOT AS FAR AS I KNOW'.

Can you help me to learn more?

(Another definition for not as far as i know that I've seen is " No-one's told me otherwise".)

I've seen this clue in The Independent.
