Evergreen version 3.1
Prior to the use of display fields in the catalog, the record used to display a full subject heading with all subfields. The resulting search when the subject link was clicked would then depend on where the user clicked the link, allowing them to choose to search just the subfield a piece of the subject heading or getting more specific by searching the entire heading.
In 3.1, we see at least three changes in behavior/appearance:
1. We aren't displaying the full subject heading. Looking at record 28 in the Concerto dataset, for example, we are missing the subfield t information from the Ludwig van Beethoven subject headings. This also makes it appear as if we have duplicate subject headings on the record (see attached screenshot)
2. When clicking the subject link, we no longer have the option to click just the subfield a portion of the heading if we want a broader search. Looking at record 28 once again, if I click the Overtures - Analysis appreciation link, I can only search that entire subject heading. I can't choose to just click the Overtures portion of the heading to make my search broader.
3. The previous subject headings used > as a separator between some subfields. It's not using a hyphen. The > was previously used as a visual indicator that there was a hierarchy to these subject headings.
After we have upgraded to 3.1.4 it turned out that the behavior of the uncontrolled subject term links in the field 653 has changed similarly to behavior described above.
In our previous Evergreen version (2.12) when the individual term in the field 653 $a had been clicked on, the individual term was used as the search query link.
In 3.1.4 when clicking the individual term, all term of all $a subfield are used as search query link.
For example: If the field 653 has following subfields: ‡aetika ‡amorální hodnoty ‡aetické principy ‡aAristoteles ‡aAristotle ‡aVirtue ‡aEthics ‡aValues
- in 2.12 when clicking on link „Ethics“ in the "Search for related items by subject" section , the created search query used to be "Ethics";
- in 3.1 when clicking on link „Ethics“ in the "Search for related items by subject" section, the search query created is no more „Ethics, but "etika morální hodnoty etické principy Aristoteles Aristotle Virtue Ethics" instead (see e.g. https:/
(As we have many older records in the library catalog with no other subject terms than those in field 653,I find this to be quite serious problem for us.)
