Description emjhet 2018-07-26 00:18:00 UTC
In Koha -- Administration -- System Preferences -- Cataloging -- Item Record --

under "item-level-itypes" we have selected "use the item type of the {specific item} as the authoritative item type (for determining circulation and fine rules, for displaying an item type icon on either opac detail or results page, etc)."

however, when you do an advanced search for an item type, the search results pull from both the item record AND the bibliographic record. 

I have a few problems with this. 
1) How was I suppose to know that, when doing an advanced search, after selecting what I wanted as my authoritative item type, that advanced searches were not covered in the "etc" of the description? When I run reports requesting these item types they could not be found, because the reports were looking for item records with the specified item types, not bibliographic records with a specific field in the 942$c. It almost seems as though this is a Koha to MARC mapping issue, except only one MARC field can be mapped to any one Koha field and in this case, two fields are being mapped to the same field. When the item record item type and the bibliographic 942$c were the same, it did not result in twice the number of results -- so???
2) I have read the Koha manual. I have never found a place where terms are defined. Is there somewhere that this information is found -- where it states "when you search for item type in the opac field A, B, and C is searched." That does not seem to be what the Koha to MARC mapping indicates. And that language does not seem to match the Koha Search Indexes. Is there no way to use the same language to indicate the same things?

I am not sure I understood correctly, but I will try and answer you anyway :)

When you search by item type, Zebra will be queried with "mc-itype: BK" (BK for Book), mc-itype is defined and mapped in the different config files of Zebra.

For instance in etc/zebradb/marc_defs/marc21/biblios/biblio-koha-indexdefs.xml you will notice that itype is indexed with values from 942$c and 952$y.
Feel free to adjust this configuration depending on your needs (a full reindexation will be needed for the changes to be taken into account).

This reads more like a support request and is almost 2 years old without more updates. Closing invalid.
