[Koha-devel] 16.05, zebra and jessie

[Barton Chittenden]

I haven't run into the issue with the dashes in idzebra-2.0 2.0.59, but I
have run into this, when using ICU-Chains:

Bug 16581 : ICU tokenization bug in idzebra-2.0 2.0.59-1
URL       : https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=16581
Priority  : P5 - low
Urgency   : enhancement
Status    : NEW

I also know that when use_zebra_facets was first introduced, it was *very*
slow -- I can't find any bugs about that though. It's possible that it got
so slow under idzebra-2.0 2.61 that the searches are timing out.

It should be possible to set the logging for zebra so that you can see the
PQF queries:

See

Bug 15714 : Remove zebra.log from debian scripts and add optional log levels
URL       : https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=15714
Priority  : P5 - low
Urgency   : enhancement
Status    : RESOLVED

For setting the log levels

And http://koha.1045719.n5.nabble.com/Improving-Zebra-logging-td5861827.html

For a general discussion of how to use them.

... This should give you some idea of what's failing, both in terms of the
dashes in 2.0.59 and the non-functional zebra facets under 2.0.61.

My general feeling is that 2.0.59 is irredeemably broken by bug 16581, and
we need at least 2.0.60, but I don't have any experience with zebra facets.
