[Koha] Advanced search - "Audience" limiter

[Justin Davis]

Hello All,

I'm running Koha 3.0.3 & am trying to figure out how to make use of the 
"Audience" limiter within the advanced search. From looking at the 
documentation 
(http://koha.org/documentation/manual/3.0/searching/guide-to-searching/common-command-language-searching), 
it looks like the "aud" notation relies on a specific index, I just 
can't figure out what that index is. There is no mention of it (that I 
can find) in the z39.50 Bib-1 attribute documentation.

Can anyone point me in the right direction? The only relevant MARC21 
field definition that I can find is the "521 - Target Audience Note". Am 
I missing something in the Koha<->MARC mapping definition?

Thank you kindly,
Justin Davis
