The issue concerning the presence of "NOT" in logical combinations.

[tyleslove]

When using Hyperscan, it has been observed that the NOT matching in logical combinations does not achieve the expected results.

ex:
1: A
2: B
3: 1&!2
4: !1&2
input data: "AB"

The data hits rule 3, while rule 4 doesn't, but what I expected was that neither 3 nor 4 would be hit. This is clearly different from the result I anticipated.

The matching result of logical combination is offset based.
So there's no problem.
