Claim 12:
13. A non-transitory computer-readable storage medium having stored thereon executable instructions that, as a result of being executed by one or more processors of a computer system, cause the computer system to at least:
acquire a set of value sequences that match a filter, wherein the filter is defined by a regular expression;
generate a flow network using a set of token sequences derived from the set of value sequences, the flow network comprising a first path representing a first token sequence of the set of token sequences and a second path representing a second token sequence of the set of token sequences, and each node in the flow network representing one or more tokens of the set of token sequences;
