Did introduce a climbing plant and searched for water (7)
I believe the answer is:
divined
'searched for water' is the definition.
'divined' can be an answer for 'searched' (divining is a kind of searching). I'm not sure about the 'for water' bit.
'did introduce a climbing plant' is the wordplay.
I cannot really see how this works, but
'climbing plant' could be 'vine' (I've seen this in another clue) and 'vine' is found within the answer.
The remaining letters 'did' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for divined that I've seen before include "forecast" , "foretold" .)
