[Koha-devel] trying to understand zebra results

[Nicholas van Oudtshoorn]

Hello all!

Here at PBC, I'm in the process of trying to relink all of our biblios 
to the right authority files. Somehow, they were an /incredible/ mess. 
I've created the authority records okay, but when trying to run 
link_bibs_to_authorities.pl, it links them to the wrong places.

Investigating, it seems like zebra isn't giving the right search results 
back.

I can confirm this in yaz-client using the query that is created by 
koha. Searching for "Bentley, Peter, Ed." returns 4 results, only two of 
which are close. Actually, the record I'm trying to match is "Bentley, 
Peter, (Ed.)" - the last option.

Interestingly enough, if I search for "Bentley, 
3432531531532513985735981<anything at all here>" it will also show me 
the same four results.
So does searching for "Bentley 513513531513515151".
But searching for "Bentleyr435435151551251" shows no results, as I would 
expect.

Am afraid I'm stumped here. PQF seems quite horrendously confusing. What 
do the numbers mean, in what context etc. Tried reading the indexdata 
manual, and still have no clue!

Can anyone shed any light?
