[Koha] OPAC Search: No result found!

[Igbudu Tersoo]

Hi,

i am using koha 17.11.02 installed on ubuntu 16.04 and MariaDB 10.0.33.
when searching the content of my OPAC it displays "No result found! " . and
from the koha about page i noticed this error "zebra server seems not to be
available. is it started?"  then i entered this command sudo
koha-rebuild-zebra -v -f library. it was ok. but after a while same error
displayed when searching OPAC. what can i do to correct this permanently?
I remain very grateful.
