[Koha] OPAC search showing no tite

[Admire Mutsikiwa]

I have upgrade my koha instance through several versions. I  have re-indexed
but I am getting the following message 

koha at libsys:~$ /usr/share/koha/bin/migration_tools/rebuild_zebra.pl -b -r -x
-v

given is experimental at /usr/share/koha/lib/Koha/DateUtils.pm line 133.

Useless use of '\'; doesn't escape metacharacter '(' at
/usr/share/koha/lib/C4/AuthoritiesMarc.pm line 848.

 

When I do  an  OPAC search,  I am getting 

 

No title
<http://10.12.1.24/cgi-bin/koha/opac-detail.pl?biblionumber=&query_desc=kw%2
Cwrdl%3A%20warfare>   Publication: Availability: No items available

 

Any help would be greatly appreciated
