I'm a little stuck... Click here to teach me more about this clue!

'comprehensive' is the definition.
(I've seen this in another clue)

Can you help me to learn more?

(Other definitions for detailed that I've seen before include "Comprehensive" , "Showing attention to fine features" , "Elaborate" , "supplying full particulars" , "Particular" .)

I've seen this clue in The Independent.
