[Koha] Fwd: Facets missing on fresh dev install of 3.18.3

[Tomas Cohen Arazi]

Setting <use_zebra_facets>0</use_zebra_facets> is not making Koha use
GRS-1. You're safe switching it.

It only falls back to the old calculation method that wouldn't calculate
the facets out of the result set, but from a small number of records from
the results. It is "less precise".

The way to debug it, is to connect to zebra yourself, and check what's
going on.

If you launch zebra manually (like in $ zebrasrv -f
~/koha-dev/etc/koha-conf.xml ) you will see the logging on your terminal.
Perform a search in the browser. You should see a line like this in the
zebrasrv terminal:

12:23:57-03/02 zebrasrv(2) [request] Search biblios OK 1014 1 1+0 RPN
@attrset Bib-1 @or @or @attr 4=6 @attr 5=1 @attr 1=1016 @attr 2=102 a @attr
4=6 @attr 5=1 @attr 9=20 @attr 2=102 a @attr 4=6 @attr 5=1 @attr 9=34 @attr
2=102 a

After that, you could see something like this, which means zebra is
actually being asked for the facets:

12:23:58-03/02 zebrasrv(2) [log] facet first phase real=0.28 cat=index

Anyway, connect to zebra manually like this (replace the PATH with yours, a
bare minimum would require substituting tcohen for your username):

$ yaz-client unix:/home/tcohen/koha-dev/var/run/zebradb/bibliosocket

and you will see a prompt like this:

Z>

Type the following:

Z> base biblios
Z> format xml
Z> elem zebra::facet::au:0:100

Now perform the same search you did on the previous step, type an 'f' and
after a space copy and paste from zebrasrv log, just after the RPN word):

Z> f @attrset Bib-1 @or @or @attr 4=6 @attr 5=1 @attr 1=1016 @attr 2=102 a
@attr 4=6 @attr 5=1 @attr 9=20 @attr 2=102 a @attr 4=6 @attr 5=1 @attr 9=34
@attr 2=102 a

Retrieve the facet:

Z> s 1+1

If you see some XML output, with author names, it means Zebra succeeds
generating the facets, and there's something wrong in Koha. Otherwise, we
should take a more sensitive look at your Zebra configuration files. But
lets start with this simple test.

Good luck!
