{{Messagebox|boxtype=note|Note text=Elasticsearch is a prerequisite for the operation of Advanced Search. The steps listed here are optional and only required if you plan to use them in your BlueSpice installation.}}
==Adding the package sources==
Elasticsearch is not included in the package manager on Debian. However, the manufacturer provides a repository for the software. Add it with the following commands to your Debian installation. Prerequisite is that you have installed the program "gnupg" (<code>apt install gnupg</code>).

<pre>wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | apt-key add -; \
echo "deb https://artifacts.elastic.co/packages/6.x/apt stable main" > /etc/apt/sources.list.d/elastic-6.x.list
</pre>

==Installing Elasticsearch==
The subsequent installation of Elasticsearch will guide you through these commands.

<pre>apt update; \
apt install elasticsearch; \
apt clean
</pre>

==Installing ingest-attachment==
For the advanced search in BlueSpice you need the plugin "ingest-attachment" for Elasticsearch. This Install it with the following command:

<pre>/usr/share/elasticsearch/bin/elasticsearch-plugin install -b ingest-attachment</pre>

==Start Elasticsearch and add it to startup==
Add the Elasticsearch to  startup and then start the service:

<pre>systemctl enable elasticsearch; \
service elasticsearch start</pre>

==Next step==
If you have completed all steps successfully, you can proceed to the next step "[[Setup:Installation Guide/System Preparation/Linux/Python|Python]]".
