Return query conditions which will match the specified string.
There are several kinds of filter entry:
*.domain.com - Matches domain.com and www.domain.com domain.com - Matches domain.com or domain.com/ but not www.domain.com *.domain.com/x - Matches domain.com/xy or www.domain.com/xy. Also probably matches domain.com/foobar/xy due to limitations of LIKE syntax. domain.com/x - Matches domain.com/xy but not www.domain.com/xy 192.0.2.* - Matches any IP in 192.0.2.0/24. Can also have a path appended. [2001:db8::*] - Matches any IP in 2001:db8::/112. Can also have a path appended. [2001:db8:*] - Matches any IP in 2001:db8::/32. Can also have a path appended. foo@domain.com - With protocol 'mailto:', matches the email address foo@domain.com. *@domain.com - With protocol 'mailto:', matches any email address at domain.com, but not subdomains like foo@mail.domain.com
Asterisks in any other location are considered invalid.
