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?
