Given a value, checks if the value matches at least one of the item's values exactly.
flag = notesItem .Contains( value )
value
String, number, or variant of type DATE.
This method cannot search a text item to see if it contains a specific word -- rather, it's intended to check a text list, number list, or date-time range to see if one of the values in the list or range matches value.
If value is a distinguished name and if the item contains Notes® user names, the distinguished name matches the common version of the hierarchical name.
