When values include the following characters—space, single quotation marks (‘), double quotation marks (“ ), curly braces ({}) , brackets ([ ]), or commas (,)—you must enclose the value in quotation marks (“ “ ) or use a backslash (\) before the character.
To enter words or letters separated by a space, such as a full name with a first name and last name, enclose the words in quotation marks. For example:
"Chris Bee"
To enter multiple values, separate values with a space, and enclose the values with brackets. For example:
[192.0.2.24 192.0.4.25]
To enter a number using a regular expression, use backslashes (\) to escape the brackets. For example:
\[0-9\]
