a bit verbose and most likely not optimal:
can probably generalize this to specify any number of fields AND-ed together.....
That's not correct because it only accounts for cases where one line's field pair matches another line's field pair. The case where a line's fields are substrings of fields of two different lines is unaccounted for.
