See bug 13665 - Retrieve facets from zebra is slow To understand why and when use_zebra_facet=1 is slow 2016-08-22 21:31 GMT+01:00 Barton Chittenden <barton@bywatersolutions.com>:
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.

Greetings,
Similar problem. I hope someone has a better solution than setting it to 0.

Hello!
We're trying to find the correction combination. We're new on Jessie, so we still have some tweaking needed...
- By default, we get zebra 2.00.59 installed on Jessie through the packages. - On 16.05, we get some very bad results in the search when the itemtype contains an hyphen (-), like 'A-DOC'. - So we installed zebra 2.00.62. This fixes the search... - But now we do not have facets. - So we set <use_zebra_facets>0</use_zebra_facets> - And now we have facets. But this feels... wrong?
My dummy question: what is the supposedly correct version of Zebra on Jessie ? And we're we correct in setting the config to 0 ?
