•
* matches any number of characters excluding dot (.). It can be used only once in a keyword and
must be at the beginning or in the middle. It cannot be used at the end or next to ^ or $.
•
A keyword with ^ at the beginning or $ at the end indicates an exact match. For example, keyword
^webfilter matches website addresses starting with webfilter (such as webfilter.com.cn) or
containing webfilter at the beginning of a string after a dot (such as
cmm.webfilter-any.com). Keyword ^webfilter$ matches website addresses containing
standalone word webfilter like www.webfilter.com; it does not match website addresses like
www.webfilter-china.com.
•
A keyword with no wildcard used at the beginning and end indicates a fuzzy match, and matches
website addresses containing the keyword.
•
If you use * at the beginning of a keyword, you must use it in the format like *.xxx, for example,
*.com or *.webfilter.com.
•
A filtering keyword with only numerals is invalid. To filter a website address like www.123.com,
you can define a keyword like ^123$, www.123.com, or 123.com, instead of 123. In other
words, you are recommended to use exact match to filter such website addresses.
