Thank you for all the prompt and helpful replies. The most precise and
complete "magic incantation" came from Larry Dixon of the Library of
Congress:
Exact match in Z39.50 is accomplished by using additional
attributes. See the attribute table in the Bath Profile. [1]
Below is a real-world example -- user is attempting to locate the
journal "Canadian Poetry" and doesn't know any of the unique
identifiers associated with it. A keyword search for "Canadian
poetry" gets 90 hits -- exact match gets 3.
Z> f @attr 1=4 "canadian poetry"
Number of hits: 90
Z> f @attr 1=4 @attr 2=3 @attr 3=1 @attr 4=1 @attr 5=100
@attr 6=3 "canadian poetry"
Number of hits: 3
This query takes advantage of many additional attribute types/names as
alluded to by Tim Shearer: use/title, relation/equal, position/first
in field, structure/phrase, truncation/do not truncate, and
completeness/complete field. It would have taken me a long, long time
to figure this out, and luckily my server supports it.
Wow, isn't the Internet cool, and /me wonders, "Did the Bath Profile
come from... Bath? [2]"
