[Koha-zebra] Exact searches with zebra.

[Henri-Damien LAURENT]

Hi,
I am trying to provide exact search in zebra for authorities.
But I have a problem :
using @attr 4=1 @attr 6=3 "TEST -- My record"
double -- are not taken into account.
and it doesnot find any results since -- is recorded in a field.
If I test without @attr 6=3 it works, but what if i have a second one
which contains TEST -- My record -- special ?
I bet both of them will be returned.


I searched the documentation but couldnot find where jokers should be
defined nor how to escape them.
Does anyone has a link ?
