We would find it very helpful if the tag and the search index were displayed in the search. Sometimes the tags are not self-explanatory, there are multiple similar tags or there are different ways to name it. So, one must regularly check the list (https://knowledge.exlibrisgroup.com/Alma/Product_Documentation/010Alma_Online_Help_(English)/Metadata_Management/180Search_Indexes/050MARC_21_Search_Indexes) to see what the exact designation is.
So if the field code (= search index) were provided as well, it would be very helpful. This way, one could search by tag or search index.

Thanks for your help !
