Search

Description

The search service requires a separate Elastic Search installation and service setup.

Use of the service is justified in the following cases:

Use of DVR-based services: access to TV program archive and EPG VOD
VOD usage

The search is done by:

names of the channels available to the subscriber according to the current tariff plan.
the name of the TV channels available to the subscriber according to the current tariff plan and the depth of the archive.
VOD library items

Installing

Elasticsearch can be installed either on the server with TMS or separately, depending on available resources.

Below is a guide for installing on Ubuntu:

sudo echo "deb http://deb.packages.tvip.tv/ xenial main" >> /etc/apt/sources.list.d/tms.list
sudo wget --quiet -O - http://deb.packages.tvip.tv/deploy/key.asc | apt-key add -
sudo apt-get update
sudo apt-get install elasticsearch

Edit the options in the /etc/elasticsearch/elasticsearch.yml configuration file:

indices.memory.index_buffer_size: "30%"
network.host: 0.0.0.0
http.port: 9200
discovery.type: single-node
xpack.security.enabled: true
xpack.security.enrollment.enabled: true
xpack.security.http.ssl:
  enabled: false
xpack.security.transport.ssl:
  enabled: false
http.host: 0.0.0.0

Attention

The http.host 0.0.0.0 option is only required in the configuration if Elasticsearch and TMS are installed on different servers, otherwise it is not mandatory.

Enabling elasticsearch autoloading and startup:

sudo systemctl enable elasticsearch
sudo systemctl start  elasticsearch

Add a tms user with super user rights and a strong password:

/usr/share/elasticsearch/bin/elasticsearch-users  useradd tms -r superuser -p your_password

Edit the TVIP TMS Search Manager configuration according to the Elastic Search settings.

After editing the configuration file it is necessary to restart the manager-tvip-tms-search

systemctl restart manager-tvip-tms-search

Attention

When installing Elasticsearch on a server with TMS, we recommend setting the RAM usage limit with the -Xmx*g parameter in the /etc/elasticsearch/jvm.options file. * is the value in Gb.
