Comb
A comb was a small object with multiple narrowly-spaced projections called "teeth", used to style hair.

In 2268,  borrowed James T. Kirk's comb to fix her hair. ()

To comb something meant to search it extensively. Bele accused Lokai of having combed the galaxy and still not found what he was looking for. ()

In 2370, Benjamin Sisko said he and Jadzia Dax had combed through data on uninhabited Class M planets in the sector surrounding Deep Space 9, and found Draylon II to be a possible new homeworld for the Skrreea. ()

In Sisko's 2373 captain's log, he mentioned combing the Demilitarized Zone for Michael Eddington. ()

To go over something with a fine tooth comb was a metaphor for looking it over extremely closely and carefully. In 2371, Captain Kathryn Janeway instructed Tuvok to tell B'Elanna Torres to go over damaged sensor logs with a fine tooth comb. ()
