Additional Comments
Expander triangle

Use the is in operator to find out whether a string contains a substring.

Parameters:

The substring and string are both strings, or expressions that evaluate to strings.

Comments:

The expression

firstString is in secondString

is equivalent to

secondString contains firstString

The is in operator is the logical inverse of the is not in operator. When one is true, the other is false.
