Elastisch is a battle tested, small but feature rich and well documented Clojure client for ElasticSearch. It supports virtually every Elastic Search feature and has solid documentation.

2.0.0-beta4 is a preview release of Elastisch 2.0, which focuses on the new features in ElasticSearch 1.0 and 1.1 as well as some API refinements.

Changes between Elastisch 2.0.0-beta3 and 2.0.0-beta4

Options As Maps

Elastisch has tranditionally accepted options as (pseudo) keywrod arguments, e.g.

(doc/search index-name mapping-type :query (q/term :biography "say"))

Starting with 2.0.0-beta4, passing a single map of arguments is now also supported by nearly all document, index, admin and percolation functions:

(doc/search index-name mapping-type {:query (q/term :biography "say")})

As a new design rule, all new API elements (e.g. aggregations) will accept a single map of options.

GH issue: #59.

Percolation of Existing Documents (REST API)

REST API client now supports percolation of existing documents:

(require '[ :as pcl])

(pcl/percolate-existing "articles" "article" "123")

Changes between Elastisch 2.0.0-beta2 and 2.0.0-beta3

ElasticSearch Client Update

ElasticSearch client has been upgraded to 1.1.0.

Clojure 1.6

Elastisch now depends on org.clojure/clojure version 1.6.0. It is still compatible with Clojure 1.4 and if your project.clj depends on a different version, it will be used, but 1.6 is the default now.

Type Exists Operation

types-exists support in both rest and native clients:

(require '[ :as esi])

(esi/type-exists? "an-index" "a-type")
