Use "search-party" in a sentence
"In his aching mind, Crozier saw at least one other Naval expedition setting sail for Baffin Bay in search of the lost Franklins this coming summer and most probably even a third Naval squadron sent all the way around Cape Horn to rendezvous, theoretically, with the other search-party ships near the Bering Strait, searching for them in the western arctic, to which Erebus and Terror had never come within a thousand miles."
"His search-party, too, had looked awkward there, having rushed to the task of investigation — some in their shirt sleeves, others in their leather aprons, and all much stained — just as they had come from their work of barking, and not in their Sherton marketing attire; while Creedle, with his ropes and grapnels and air of impending tragedy, had added melancholy to gawkiness."
"That will give us the excuse to send a search-party back in that area to look for her, once you're sure she's gone quite mad!"
