{ 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$, www.123.com, or 123 .co m, instead of 123 . HP
recommends you to use exact match to filter such website addresses.
2. Wildcard usage in URL parameter filtering keywords:
{ The caret (^) matches the beginning of the string. It can be used only once in a keyword and
must be at the beginning.
{ The dollar sign ($) matches the end of the string. It can be used only once in a keyword and
must be at the end.
{ The ampersand sign (&) matches any single character. It can be used for multiple times in a
keyword, consecutively or non-consecutively. It can appear at any position of a keyword, but
cannot be used next to *.
{ The asterisk (*) matches any string of up to 4 characters, including spaces. It can be used only
once in a keyword and must not be at the beginning or end.
{ A keyword with ^ at the beginning or $ at the end indicates an exact match. For example,
keyword ^webfilter$ matches URLs containing standalone word webfilter, like
www.abc.com/webfilter any; it does not match URLs like www.abc.com/webfilterany.
{ A keyword with no wildcard used at the beginning and end indicates a fuzzy match, and
matches URLs containing the keyword.
