[Koha] Zebra server update and Elastic Search

[Luis Moises Rojas]

Hello,
We have Koha  19.11.08.000  on ubuntu 18.04.1 LTS, zebra version Zebra
2.0.59
We want to upgrade to zebra 2.1.14 to see if we can fix our sort error.

Also, we had installed ElasticSearch  Nodos: localhost:9200 | Estado: en
ejecución | Índices: koha_bijrdlibrary_biblios (conteo: -1),
koha_bijrdlibrary_authorities (conteo: -1)
What -1 means?

It is possible to upgrade Zebra to fix it?

Thanks.
