Performs logical negation. Carries out a logical NOT operation on the given value(s) and produceds the resulting true or false value(s).
<not true,false,true>
— produces false,true,false
, being the logical negation of the primary field.
<not|le 5,10>
— produces false
. (It is true that 5 is less than or equal to 10 but this takes the logical negation: 5 is not greater than 10.)
Once the tag is complete, evaluates each value in the primary field as being either true or false, then for each true/false value, produces its logical negation. The lifetime of the not tag then ends.
