Hello everyone,

I'm currently facing an issue with a new Z3950 authority server
integrated with ElasticSearch that I'm trying to set up. My basic
searches are functioning properly, but when I attempt to use @attr
attributes, it doesn't seem to work. Interestingly, attribute 1=1
(personal name) works fine. I've attempted to address this by adding the
attributes in the /etc/z3950/attribute_mappings.yaml file, but
unfortunately, that hasn't resolved the issue.

This situation has led me to question whether it's possible, with
ElasticSearch for authorities, to perform a search on a specific field,
such as a title by adding @attr 1=4 on yaz-client command line. In
contrast, I haven't encountered this problem with an authority server
under ZEBRA. For example, when I use @attr 1=4, it works seamlessly, but
with ElasticSearch, it's not functioning as expected.

Example

Utilizing a Z3950 authority server with ElasticSearch, the yaz-client
connects successfully to Koha/GFS/YAZ (Version 21.05.11.000/5.27.1).
However, when attempting searches for 'canada' with the attribute '@attr
1=4', the number of results (56811) remains the same, '@attr 1=4' does
not have effect.

I aim to enable the functionality of attributes to be able to search via
these field
         nameany           => '@attr 1=1002 "#term" ',
         authorany         => '@attr 1=1003 "#term" ',
         authorcorp        => '@attr 1=2 "#term" ',
         authorpersonal    => '@attr 1=1 "#term" ',
         authormeetingcon  => '@attr 1=3 "#term" ',
         subject           => '@attr 1=21 "#term" ',
         subjectsubdiv     => '@attr 1=47 "#term" ',
         title             => '@attr 1=4 "#term" ',
         uniformtitle      => '@attr 1=6 "#term" ',
         srchany           => '@attr 1=1016 "#term" ',
         controlnumber     => '@attr 1=12 "#term" ',


Do you have any suggestion/check to fix this situation ?

Cheers
