- There may actually be a way to do this without extending the protocol,
- by making a minor change in the gopher clients.
-
- When I use a WAIS client (e.g. xwaisq) and send the WAIS server a null
- search string, I sometimes get back two items:
-
- 1000 9.5K Information on database: Aesop-Fables
- 1000 48.5K Catalog for database: Aesop-Fables
-
- However, when I use a gopher client (e.g. Unix curses gopher 1.03 or
- xgopher 1.1) and try to send a null search string, the client assumes
- I've made a mistake and doesn't submit the query to the WAIS server.
- Is this a bug or a feature?
-
- The "Information on database" item is a logical place to put a
- description of what flavor of WAIS searching the server uses, as well
- as other important information typically kept in Gopher "About" files
- (name and contact info of the data maintainer; description, origin, and
- authority of the data; frequency with which the data is updated; any
- known omissions, problems or "bugs" in the data).
-
- Unfortunately, not all WAIS servers return the "Information on
- database" in response to a null query, and those that do often return a
- relatively uninformative boilerplate message automatically generated by
- waisindex. Clearly for this method to be generally useful, it would
- require the cooperation of the maintainers of WAIS servers as well as a
- change in the gopher clients.
