Currently adding fields and values to Alma Advanced Search is only possible one by one. This is a painfully slow and click-heavy activity when there are many parameters to be added. This also risks slowing down Alma UI when upwards of several hundred fields (as advised by Ex Libris Support).
It is proposed to support many values to be copy and pasted in to a single field by a string with separator, such as an OR Boolean or semi-colon representing the OR.

Use case: We use a logical set to fuel our Collection Discovery collection titled “Aboriginal and Torres Strait Islander authors”. We’re now in the process of shifting this from a curated collection by manual addition of a bibliographic local field to a single work for the author to a comprehensive collection for all works we hold by the Authority IDs for the identified authors. We have already contributed more than 70 new LCNAMES Authorities via NACO membership as part of this work supporting recognition of First Nations peoples and for our faculty to indigenise their curriculum by ease of ability to find our related holdings in Primo by Collection facet and collection. However, Alma makes this process difficult in our logical set in having to one by one add the Authority IDs. Ex Libris confirmed there is no current functionality to meet this need.

Example string for Authority ID contains phrase no2025050743 OR no2025048340 OR no2025018153 OR no2025013888 OR no00089878 OR no2025019805 OR no2025026097 OR no2025018142 OR no2025018141 OR no2025061608 OR no2025019804 OR no2025020415 OR no2025030597 OR n93058348 OR no2025034631 OR no2025022265
