I think you may be getting confused here. You don't need the
apostrophes or the square brackets. Just type your strings in. This
is why I think the | method for ORing to strings can be ambiguous.

I'm not sure about the spaces. Again, this is another reason I find
the | method to be ambiguous.

False.

As far as I know, no. In a *single* string set, you could only do the
C and D and (E or F). See my example in a previous post to this
thread.

Just be careful here. You can not have a single string that says
something like,
(Tom or Jane) Doe
Instead you would need to break it up into either
Tom|Jane AND Doe
or
Tom Doe|Jane Doe

See above.

Nope. Regular expressions are complex, but they are much different
than the "simple" search strings you've been looking for.
