Question

我正在尝试使用clojure弹性搜索API Elastisch。

我正在按照文档中给出的演示代码进行操作我正在为以下代码获取文档/索引创建输出

(defn demo-search-connect []
  (esr/connect! "http://127.0.0.1:9200")
  (let [mapping-types {:person {:properties {:username   {:type "string" :store "yes"}
                                         :first-name {:type "string" :store "yes"}
                                         :last-name  {:type "string"}
                                         :age        {:type "integer"}
                                         :title      {:type "string" :analyzer
                                          "snowball"}
                                         :planet     {:type "string"}
                                         :biography  {:type "string" :analyzer   "snowball" :term_vector "with_positions_offsets"}}}}
    doc {:username "happyjoe" :first-name "Joe" :last-name "Smith" :age 30 :title "Teh Boss" :planet "Earth" :biography "N/A"}]

 (esi/create "myapp2_development" :mappings mapping-types)
;; adds a document to the index, id is automatically generated by ElasticSearch
;= {:ok true, :_index people, :_type person, :_id "2vr8sP-LTRWhSKOxyWOi_Q", :_version 1}
(println (esd/create "myapp2_development" :person doc :settings {"number_of_shards" 1}))
))

;Supposed to return an output for the search query 
(defn demo-search-index [] 
  (esr/connect! "http://127.0.0.1:9200")
  (esd/search "myapp2_development" "person" :query {:term {:last_name "Smith"}})
  )

;Supposed to return the document with the given id
(defn get-document [id]
  (esr/connect! "http://127.0.0.1:9200")
  (esd/get "myapp2_development" "person" id)
  )

我得到第一个函数的输出：

{:ok true, :_index myapp2_development, :_type :person, :_id GzNdzrqhQECQDlkSbq-GHA, :_version 1}

从输出中我相信文档正在正确索引

问题是第二个和第三个函数返回：

{:took 153, :timed_out false, :_shards {:total 5, :successful 5, :failed 0}, :hits {:total 0, :max_score nil, :hits []}}

分别为

和nil。

我在这里缺少什么？

P.S：我是clojure和弹性搜索的新手

Answer 1

esd/get失败，因为您的映射类型为:person而不是"person"（关键字与字符串）。

您的代码esd/search存在同样的问题，但另外您应该将last_name更改为last-name，将"Smith"更改为"smith"，一切都应该有效

Clojure弹性搜索API Elastisch不返回结果或文档
