I can understand that. The "search" function for the list archives
seems to be rather non-functional.

Folks, is there anything we can do to enhance/fix the archive search?
Hub.org people? Right now I'm keeping my own archive so that I can
search it through Netscape!

The answer to your question, in a simplified form for using PL/pgSQL
functions to return rowsets for complex searches:

1. Create a sequence "search_sq"
2. Create a table searches (
search_sq INT4,
key_no INT4,
CONSTRAINT PRIMARY KEY search_PK (search_sq, key_no) );
3. Create a view (sv_results) that defines the column set you want to
see.
4. Create a function ("search_it") that:
a. grabs the s_key := Nextval('search_sq'),
b. INSERT INTO searches SELECT s_key, key_no from sv_results
WHERE ... (dynamically defined criteria)
c. Return the s_key from the function.
5. Query from you front-end app on sv_results JOIN searches where
search_sq = s_key.

This works quite well, especially for web applications.
