Problemas con elastick search

17 Dec 2021

      Estimados:

Cree un servidor de pruebas y le instale Elasticsearch, le cargue la BD del
servidor de producción, pero no logro que busque. La instalación es de
koha20.05 en un servidor con Debian 10 y MaríaDB

En acerca de Koha aparece en verde: “Servidores: 127.0.0.1:11211 | Espacio
de nombres: koha_kohaE | Estado: en ejecución. | Configurar lectura a
partir de: koha-conf.xml”

****************************************

Cuando ejecuto systemctl status elasticsearch.service se ve todo bien:
● elasticsearch.service - Elasticsearch

   Loaded: loaded (/lib/systemd/system/elasticsearch.service; enabled;
vendor preset: enabled)

   Active: active (running) since Fri 2021-12-17 12:24:41 -03; 35min ago

*******************************

En Koha.conf cambie la ruta que venía por defecto por la ruta donde
encontré los archivos en Debian 10

/etc/koha/sites/kohaE/searchengine/elasticsearch/

/usr/share/koha/intranet/cgi-bin/admin/searchengine/elasticsearch/

Y quedó así

<!-- Elasticsearch Configuration -->
 <elasticsearch>
     <server>localhost:9200</server> <!-- may be repeated to include all
servers on your cluster -->

      Note that any changes made to the mappings file only take effect if
you reset the mappings in
      by visiting /cgi-bin/koha/admin/searchengine/elasticsearch/
mappings.pl?op=reset&i_know_what_i_am_doing=1&reset_fields=1.
      Resetting mappings will override any changes made in the Search
engine configuration UI.

***********************************************

Al indexar, Elasticsearch me di cuenta que habían errores con las
autoridades que la zebra ignora y los corregí, pero hubo un error que no
supe cómo corregir, porque no  me indica en qué registro está el error.

substr outside of string at
/usr/share/koha/lib/Koha/SearchEngine/Elasticsearch.pm line 510.

Use of uninitialized value $_ in pattern match (m//) at

Los errores que me salen sond e este tipo
