Elasticsearch Erlang Client, OTP 19, rebar3
This module allows to perform different operations against a single elasticsearch cluster,
one of the most interesting features is the bulk indexing that allows to push a number
of documents to the cluster, also there is an scroll function that allows to scroll over
a set of results from the cluster, that helps to get a big quantity of documents using an
iterator, and process them as they are retrieved until the result set is done.
If environment_var atom is used as host, the module will look in the os:getenv(ENV_ELASTICSEARCH_HOST)
for the hostname, if var is not yet defined it will default to localhost.
