A new feature was added to Aleph v23 to exclude certain subfields from Ctrl+F3 search
When using Ctrl+F3 search, subfields that are not part of the heading (like e623w) are included in the search, and the exact heading in authorities is not found (usually the next heading is highlighted)
1. Add list of subfields that should be ignored when building the string for Ctrl+F3 to Col.12 of ./xxx01/pc_tab/catalog/scancode.dat .
This is what was achieved and what was omitted in this how-to.
