[Framers] Are there limits on Conditional Expressions? If so, what are they?

[Robert Lauriston]

The shorter expression in your original post:

not ( "DocIss" or "Internal" or "LP" or "LPvA" or "LPvB" or "LPvC" or "NoSeeEm"
or "SAS4vB" or "SAS4vC" or "TBP" or "WriterNote" ) or ( "SAS4" and ( "LPvB" or
"LPvC" ) ) and not ("TBP" or "Internal") or ( "SAS4vA" and ( "LPvB" or "LPvC"
) ) and not ("TBP" or "Internal")

That would return everything that has none of these tags:

( "DocIss" or "Internal" or "LP" or "LPvA" or "LPvB" or "LPvC" or "NoSeeEm"
or "SAS4vB" or "SAS4vC" or "TBP" or "WriterNote" )

plus everything selected by this statement:

( "SAS4" and ( "LPvB" or
"LPvC" ) ) and not ("TBP" or "Internal") or ( "SAS4vA" and ( "LPvB" or "LPvC"
) ) and not ("TBP" or "Internal")
