clj-elasticsearch

A clojure wrapper around the native Java Elasticsearch API. It aims to be as idiomatic as possible while remaining fast.

The API docs are available here.

Usage

For the most basic use case:

(use 'clj-elasticsearch)

(def es (make-client :transport {:hosts ["localhost:9300"] :cluster-name "elasticsearch"}))

(def index-res (index-doc es {:index "test" :type "test"
                         :source (build-doc {:field1 "foo" :field2 42})}))
(def nb-docs (:count (count-docs {:indices ["test"]})))
(def match-all "{\"query\":{\"query_string\":{\"query\":\"*:*\"}}}")
(def res (get-in (search es {:indices ["test"] :types ["test"] :extra-source match-all}) [:hits :hits]))

Vectors and hashes are converted to arrays. See the doc strings for the arguments used by each method and the javadocs for more details about their use. A convert function can be used to try to translate the returned objects to Clojure or other formats. It can be sprecified by the :format key when calling the various API methods.

You can also use the functions asynchronously by providing a callback listener with the :listener key, as such:

(count-docs es {:indices ["test"]
                :listener (make-listener
                              {:on-failure (fn [e] (throw e))
                               :on-success (fn [res] (println (convert res :clj)))})})

A bit more details can be found in the tests.
