TL;DR

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.

1.3.0-rc1 is a release candidate that is compatible with 1.2.0.

Changes between Elastisch 1.3.0-beta5 and 1.3.0-rc1

Bulk Indexing Fix

Elastisch no longer erroneously inserts _index and _type fields into documents inserted via bulk API.

Result Scrolling as Lazy Sequences

clojurewerkz.elastisch.native.document/scroll-seq and clojurewerkz.elastisch.rest.document/scroll-seq are new functions that accept a search query response and return a lazy sequence of paginated search results.

This makes working with result sets that require pagination much more natural:

1
2
3
4
5
6
7
8
9
10
11

(require '[clojurewerkz.elastisch.native.document :as doc])

(let [index-name   "articles"
      mapping-type "article"
      res-seq      (doc/scroll-seq
                       (doc/search index-name mapping-type
                                   :query (q/term :title "Emptiness")
                                   :search_type "query_then_fetch"
                                   :scroll "1m"
                                   :size 2))]
    res-seq))
