{
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$, www.123.com, or 123.com, instead of 123. H3C
recommends that you use exact match to filter such website addresses.
2. Wildcard usage in URL parameter filtering keywords:
{
The caret (^) matches the beginning of the string. It can be used only once in a keyword and
must be at the beginning.
{
The dollar sign ($) 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.
