Error:
Unable to connect to Full Text Search server, please verify settings

Solution:
1. Check ElasticSearch is running
   >  sudo /etc/init.d/elasticsearch status
2. If status is not running, restart
   >  sudo /etc/init.d/elasticsearch restart
3. If the above does not work, modify /etc/elasticsearch/elasticsearch.yml as follows:
discovery.zen.ping.multicast.enabled: false and repeat 1 & 2
