Speaker: Miloš Milojević
Elasticsearch je search server baziran na Lucene-u, napisan u Javi, i objavljen kao open source projekat. Tokom predavanja, upoznaćemo se sa terminima Symfony i Elasticsearch, kao i kako integrisati Elasticsearch engine na konkretnom Symfony projektu uz par praktičnih saveta.

6. curl -XGET ‘http://localhost:9200’ { "status" : 200, "name" : "Tutinax the Mountain-Mover", "cluster_name" : "elasticsearch", "version" : { "number" : "1.5.2", "build_hash" : "62ff9868b4c8a0c45860bebb259e21980778ab1c", "build_timestamp" : "2015-04-27T09:21:06Z", "build_snapshot" : false, "lucene_version" : "4.10.4" }, "tagline" : "You Know, for Search" }

8. -Cluster cluster.name = elasticsearch -Nodes: -Allow this node to be eligible as a master node (enabled by default): #node.master: true -Allow this node to store data (enabled by default): #node.data: true
9. You can exploit these settings to design advanced cluster topologies. Node example: 1. You want this node to never become a master node, only to hold data. This will be the "workhorse" of your cluster. node.master: false node.data: true
10. Node example: 2. You want this node to only serve as a master: to not store any data and to have free resources. This will be the "coordinator" of your cluster. node.master: true node.data: false
11. Node example: 3. You want this node to be neither master nor data node, but to act as a "search load balancer" (fetching data from nodes,aggregating results, etc.) node.master: false node.data: false
