Bug ID: 25273
Summary: Elasticsearch Authority matching is returning too many
results
Change sponsored?: ---
Product: Koha
Version: master
Hardware: All
OS: All
Status: NEW
Severity: major
Priority: P5 - low
Component: MARC Authority data support

Bug 24269 attempted to improve the authority matching process in ES, however,
it does not accomplish the full extent of what is needed.
Match-heading is used as the matching field for records, and I added
C4::Heading to be used to generate the correct form including subfields,
however, the subfields are still indexed at normally too. This is problematic
as the index for a heading like:
$aCats$vFiction$zVermont
Is indexed into match-heading as:
["Cats","Cats genresubdiv Fiction geosubdiv Vermont","Vermont"]
Thus if a record has a heading of:
Vermont
It returns the above record.
We need to index for the linker into a field that only gets the correct search
form for heading and no other data. I propose to do this by retrieving the
fields set to be copied from Administration->Authority types and indexing them
into a field that can be used only for matching/
