Hi Fridolyn,
Thank you for this. I was beginning to wonder if nobody was interested
in the question.
The bug you mention is a useful addition, but we achieved considerable
success by correcting the contents of the default.idx
(~/koha-dev/etc/zebradb/etc/default.idx) to use phrases-icu.xml for
index p, and to ensure phrases-icu.xml and words-icu.xml have the
correct stanzas for searching accent-blind.
With these both in place I believe we have a very good hit rate for
linking bib to authorities as long as the authority terms have been
de-duplicated.
I think Colin has submitted patches so that these are in place for all
moving forwards, but it is good to know that others are using these
features.
What we were seeing before was if the term in the bib was (say) "History
of Art" it would only match on the first word so would match an
authority of (say) "History Books".
All the best.

Hie,
It is because in Zebra, exact search does not work.
It can find a phrase (all words in same order) but not say if this
phrase fits the entire (sub)field. This is the purpose of PQF attribut
6, but is does not work.
So when linking bibs to authorities, linker will match more
authorities than needed. For example, in biblio record "History" will
match authorities with headings "History", "History of art", "History
of science", ...
That is wy I created Bug 9072 :

Hi.
I mentioned we also have a problem with linking bibs to authorities.
We use authorities and want to link them to bibs. Over previous
versions of Koha this has sometimes worked quite well. However on a few
systems we have at version 3.12 it seems that the Zebra search into the
authorities (used by link_bib_to_authorities) is returning all terms
that contain any of the words in the bib field.
So if the linkage is set to "default" then most authority searches will
return multiple answers which means they do not link.
If the linkage syspref is set to first or last then most of the bibs
will link to the wrong authority as it is pot luck which will be first
(or last) of the many authorities found by searching all the words ORed
together.
The only terms that will link are single-word authorities that are not
used in any other authorities.
If anyone has any pointers or knows how to get round or over this
problem I would love to hear from you. More details on request...
We are using Zebra dom indexing and icu chains and are using Koha 3.12
on Debian. We are not yet using QueryParser. Sysprefs and Help > About
