Using correlation to search for subvector within a binary time series (bitstream)

I understand how the correlation between two time series is found. I am wondering if it is possible to use a correlation method in order to find a particular sub-vector within a binary time series (e.g., a bitstream).

For example, given a pseudo-random bitstream of length 1,500, say, can one use a correlation technique to see if the vector v = [1 1 1 1 0 1] appears somewhere in the bitstream?

I am aware of Matlab's "find" function and its other built-in functions; I am curious to see if this approach is valid as well. Thanks!
