Ok, I'm replying to myself, but I think this is worth the effort.
So in the example above, the letters 'A' and 'B' are expressions which
can be true or false. In TB the specific expression is:
Is the string in the specified location?
So if we use
| = Or
& = and
! = Not
A B A|B !(A|B) A&B !(A&B) !A !B !A|!B !A&!B
Yes Yes Yes No Yes No No No No No
Yes No Yes No No Yes No Yes Yes No
No Yes Yes No No Yes Yes No Yes No
No No No Yes No Yes Yes Yes Yes Yes
