'only temporary' is the definition.
I can't tell whether this defines the answer.

'rapid repair' is the wordplay.

'repair' becomes 'fix' (synonyms).
'quick'+'fix'='QUICK-FIX'

'is' acts as a link.

Can you help me to learn more?

(Other definitions for quick fix that I've seen before include "Expedient" , "temporary solution" , "no lasting cure" .)
