Do you mean "John" or "Eric". I saw Eric Nystrom's reply; if there is 
another from "John" I have not received it. I am not being flippant.

'Tag = 'This" || Tag = 'That"' evaluates and returns each record in 
which "This" or "That" appears as well as those records in which both 
"This" and "That" are a value for Tag.

However, I want only those records which contain Tag: This and Tag: That.

I am surmising that this may be possible from the example concerning 
email addresses in 3.5.2.3 Field Values. I have tried the = and ~. As I 
also mentioned I do not want to be constrained to any order in which the 
values are entered into the record so the use of subscripts or indices 
should not be considered.
