[Koha] Downgrade koha database from 3.16.x to 3.14.x

[Dibyendra Hyoju]

Hi all,

I tried clearing all the ISBNs from isbn field in the biblioitems
table in my test database and re-indexed the zebra index but the same
problem is shown. That means it is not related to malformed ISBN,
rather could be because of malformed MARC record? The same database
works okay with Koha 3.14, which is there is no such search issues.

Any suggestions would be appreciated!

Thank you.

Regards,
Dibyendra
