I have tried googling and stuff but couldn't find any satisfactory suggestion that would mean "A desperate search for"
The closest I can proffer is-
: to search for something especially by moving and looking through the contents of a place.
: to engage in an undirected or haphazard search
v. - search haphazardly
- “We rummaged through the drawers”
n. - a search for something (often causing disorder or confusion)
- “he gave the attic a good rummage but couldn't find his skis”
"He scoured the countryside, desperate to find his dog."
verb (used with object) - to range over, as in a search: They scoured the countryside for the lost child.
verb (used without object) - to range about, as in search of something.
ransack [ran-sak] verb (used with object) 1.to search thoroughly or vigorously through (a house, receptacle, etc.): They ransacked the house for the missing letter. 2.to search through for plunder; pillage: The enemy ransacked the entire town.
