Truth value search conditions

IS [ NOT ] truth-value

Without the NOT keyword, the search condition is TRUE if the condition evaluates to the supplied truth-value, which must be one of TRUE, FALSE, or UNKNOWN. Otherwise, the value is FALSE. The NOT keyword reverses the meaning of the search condition, but leaves UNKNOWN unchanged.
