 Determines whether a specific key is present in a structure.
-**Note:** When a struct's key contains a NULL as a value, Lucee's Null Support setting affects the outcome.
-When Null Support is **false**, if a key DOES exist, and it has a NULL as a value, it will return **false**.
-When Null Support is **true**, if a key DOES exist, and it has a NULL as a value, it will return **true**.
+
+In CFML, by default, this will return `false` for any keys with a `null` value, however, if Full Null Support is enabled, it will return `true`.
