Continuously concerning search when demanded (2,7)
I believe the answer is:
on request
'continuously concerning search when demanded' is the definition.
I can't tell whether this defines the answer.
'continuously concerning search' is the wordplay.
'continuously' becomes 'on' (eg to keep on is to do something continuously).
'concerning' becomes 're' (both can mean on a particular topic).
'search' becomes 'quest' (quest is a kind of search).
'on'+'re'+'quest'='ON REQUEST'
Can you help me to learn more?
(Another definition for on request that I've seen is " When asked for".)
