This is a 7482 clarification proposal that I received off-list.
Current text:
Partial string searching uses the asterisk ('*', US-ASCII value 0x002A) character to match zero or more trailing characters. A character string representing multiple domain name labels MAY be concatenated to the end of the search pattern to limit the scope of the search. For example, the search pattern "exam*" will match "example.com" and "example.net". The search pattern "exam*.com" will match "example.com". If an asterisk appears in a search string, any label that contains the non-asterisk characters in sequence plus zero or more characters in sequence in place of the asterisk would match. Additional pattern matching processing is beyond the scope of this specification.
Proposed new text:
Partial string searching uses the asterisk ('*', US-ASCII value 0x002A) character to match zero or more trailing characters. A character string representing [a domain label suffix] MAY be concatenated to the end of the search pattern to limit the scope of the search. For example, the search pattern "exam*" will match "example.com" and "example.net". The search pattern "exam*.com" will match "example.com". If an asterisk appears in a search string, any label that contains the non-asterisk characters in sequence plus zero or more characters in sequence in place of the asterisk would match. [Only a single asterisk is allowed for a partial string search.] Additional pattern matching processing is beyond the scope of this specification.
What do people think about this proposal?
