[Koha] how to get the accession number displayed in the opac search

[satish]

Hello,

Regarding OPAC Search in Koha 3.6.2, it does not show the Accession Number
in the basic search
by defacult. For checking accesion number, we need to switch from Normal
view to MARC view.
Therefore how to set OPAC to show the accession number in its basic  search.
and which field in the marc tag responsible to fetch this result.

example: please do search in the opac in : http://lib.jncasr.ac.in/homepage/

can you please advice?

thank you
