Undocumented but since it returns a vector dependent on the inputs, unlikely it's other than just linear (in traversing memory) would be my guess. It's not looking for something in an ordered list or the like where a binary search would help.

The timings imply that it is a linear search. I did not find an evidence that it is multi-threaded, but I'd expect it to be.
As dpb said already, a binary search would be useful only if the input is sorted. The undocumented functions ismembc and ismembc2 perform a binary search.
