'search for answers?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.

'senora quiet in new' is the wordplay.
'new' is an anagram indicator.
'senora'+'quiet'+'in'='senoraquietin'
'senoraquietin' is an anagram of 'QUESTIONNAIRE'.

Can you help me to learn more?

(Other definitions for questionnaire that I've seen before include "Form for market research" , "List of enquiries" , "Form for collecting data" , "Survey answer sheet" , "List of inquiries" .)

I've seen this clue in The Times.
