+Il faut installer elasticsearch 5.*. C'est compliqué. Mais en suivant https://www.elastic.co/guide/en/elasticsearch/reference/5.4/deb.html ça va.
+
+    wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
+    sudo apt-get install apt-transport-https
+    echo "deb https://artifacts.elastic.co/packages/5.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-5.x.list

+    
+    sudo systemctl daemon-reload
+    sudo systemctl enable elasticsearch.service
+    sudo systemctl start elasticsearch.service
+
+Et puis, de retour dans le virtualenv python
+
+   python manage.py search_index --rebuild
+
+Si des erreurs s'affichent, il y a une cachuète dans le beurre.
