    Advice I read
    -------------
    http://blog.lavoie.sl/2012/09/configure-elasticsearch-on-a-single-host.html (for an old version)

    ```
    Edit /etc/security/limits.conf and add: elasticsearch hard memlock 100000
    Edit the init script: /etc/init.d/elasticsearch
    Change ES_HEAP_SIZE to 10-20% of your machine, I used 128m
    Change MAX_LOCKED_MEMORY to 100000 Be sure to set it at the same value as 1.1
    Change JAVA_OPTS to "-server"
    Edit the config file: /etc/elasticsearch/elasticsearch.yml
    index.number_of_shards: 1
    index.number_of_replicas: 0
    index.term_index_interval: 256
    index.term_index_divisor: 5
    network.host: 127.0.0.1
    network.tcp.block: true
    ```
