applies. For example, if the keyword is “^huawei”, the URL addresses beginning with
huawei (e.g. huawei.com.cn) or addresses similar to cmm.huawei-3com.com are
filtered out, but the address similar to www.bj-huawei.com is not filtered out. If the

www.huawei.com) is filtered out. The address similar to www.huawei-3com.com is
not filtered out. If fuzzy match applies, any address containing the keyword is filtered
out.
The wildcard “&” cannot replace “ . ” during address filtering.
The wildcard “*” cannot replace “.”, such as “huawei*.com”, it must be in the form
of “*.com” or “*.huawei.com” when it is present at the beginning.
