Tense searches producing unimportant stuff (7)
I believe the answer is:
trifles
'unimportant stuff' is the definition.
'tense searches' is the wordplay.
'tense' becomes 't' (abbreviation used in many dictionaries).
'searches' becomes 'rifles'.
't'+'rifles'='TRIFLES'
'producing' acts as a link.
(Other definitions for trifles that I've seen before include "Behaves frivolously for popular desserts" , "Toys" .)
