Hi all I'm a beginner in elasticsearch, and i have some questions: 1)Exists some book of ElasticSearch? 2)To add a new node i just need to start a new instance of Elasticsearch in other machine located in the same network? 3)Suppose i have two machines with elasticsearch. I need to configure apache as front end with mod-proxy to search in index to garantee failover? 4)Elasticsearch has some administration page? Thanks ---

1. No 2. yes 3. No. ES does it for you 4. not really but you have rest endpoints and you can use : [GitHub - mobz/elasticsearch-head: A web front end for an elastic search cluster](https://github.com/mobz/elasticsearch-head) [GitHub - lukas-vlcek/bigdesk: Live charts and statistics for Elasticsearch cluster.](https://github.com/lukas-vlcek/bigdesk) HTH David 😉 @dadoonet Le 1 févr. 2012 à 02:40, Anderson vasconcelos [anderson.vass@gmail.com](mailto:anderson.vass@gmail.com) a écrit : > Hi all > > I'm a beginner in elasticsearch, and i have some questions: > > 1)Exists some book of Elasticsearch? > 2)To add a new node i just need to start a new instance of > Elasticsearch in other machine located in the same network? > 3)Suppose i have two machines with elasticsearch.

Thanks for the response. 1. I start tow machines and change the name of cluster and the name of nodes. Elasticsearch just discovery the new node just when i put in discovey.zen.ping.unicast.hosts the ip of host, thats correct? 2)When i search in index, i need to use only one URL like [http://solrcluster](http://solrcluster) and this url will search all nodes. Hi i do this with Elasticsearch without apache mod\_proxy. Thanks 2012/2/1, David Pilato [david@pilato.fr](mailto:david@pilato.fr): > 1. No > 2. yes > 3.

3)Exists some API to index objects in Elasticsearch? Some API that uses Annotations?
