Bug 17123

Srdjan, could you be more specific on how to reproduce it?

Unfortunately I cannot at the moment, it must be a combination of things introduced relatively recently to the master. I have not been playing with OPAC for a month or so, and this thing jumped on me. What I did meanwhile as well was to move zebra indexing to dom.
I'll try to see what exactly is causing it.

This error usually happens when you zebra index is not up-to-date.

Hello,

I have the same problem, someone has the solution, please?

Thanks!

Hi Gabrielo, did you update your zebra index?

Hi, Jhonathan

Thanks for replying so quickly, look

I take it from the zebra page, but it seems that I do not update 

Debian users can add the following two lines in /etc/apt/sources.list
and use Debians own package management tools, apt-get, aptitude, or dselect.
Replace xxxxx with jessie, wheezy, etc.
As of June 2015,  Debian wheezy (7) is obsolete stable.
Debian jessie (8) is current stable.

deb http://ftp.indexdata.dk/debian xxxxx main
deb-src http://ftp.indexdata.dk/debian xxxxx main

These packages are signed with a key you can install as follows:
 wget http://ftp.indexdata.dk/debian/indexdata.asc
 sudo apt-key add indexdata.asc

Installed:
Zebra 2.0.44 (C) 1994-2010, Index Data ApS Zebra is free software

Gabrielo, did you fully rebuild your zebra index using the koha-rebuild-zebra command?

Hi,

Yes, look:

sudo apt-get update
sudo koha-rebuild-zebra -f -v 
sudo service apache2 restart

But, the update is not done.

... Does not work anyway

On v17.11.07. I have the same issue but just with small keywords on the query, like opac-search.pl?q=a and q=aa
No changes with koha-rebuild-zebra -f -a -b -v instance, restarting services apache2 koha-common or rebooting.

The referenced line (Search.pm line 813):
# get the facet record from result set
my $facet = $rs->record( 0 )->raw;

Maybe is a timeout error/issue (2GB RAM, 1 vCPU). Happen after ~35 seconds of waiting. When searching zebrasrv (or starman worker) consume high percentages of CPU and then on plack-error.log (without any timestamp, but tested several times with tail -f):
Use of uninitialized value $error in concatenation (.) or string at /usr/share/koha/opac/cgi-bin/opac/opac-search.pl line 615
$template->param(query_error => $error.$@);
https://github.com/Koha-Community/Koha/blob/master/opac/opac-search.pl#L615

zebra-output.log just have the eternal classic log:
  zebrasrv(42) [warn] ir_session (exception)
zebra-error.log probably because the restarts/reboots
  killed by signal 15, stopping

There's really not enough information to proceed on this one.

However, Pablo's issue can be alleviated by updating zebra_connection_timeout in koha-conf.xml thanks to bug 31614
