Port of RSolr to Elixir

1. Add exsolr to your list of dependencies in mix.exs:

def deps do
  [{:exsolr, git: "http://github.com/dcarneiro/exsolr"}]
end

2. Ensure exsolr is started before your application:

   def application do [applications: [:exsolr]] end

The default behaviour is to configure using the config file:

In config/config.exs, add:

config :exsolr,
  hostname: "localhost",
  port: 8983,
  core: "elixir_test"

Use #get to perform a query into Solr. All parameters are optional

response = Exsolr.get(q: "roses", fq: ["blue", "violet"])
Enum.map(response["docs"], fn(doc) -> doc["id"] end)

The following query fields will have default values if they aren't specified

q:     "*:*"
wt:    "json"
start: 0
rows:  10

Single document via #add

  Exsolr.add(%{id: 1, price: 1.00})

Multiple documents via #add

  [%{id: 1, price: 1.00}, %{id: 2, price: 10.50}]
  |> Exsolr.add

Force a commit into Solr

Exsolr.commit

Delete by id

Exsolr.delete_by_id("1")

Delete all the documents from the core

Exsolr.delete_all
