我正在尝试 clojure 弹性搜索 API Elastisch。

我正在关注文档中给出的演示代码，我正在为以下代码获取文档/索引创建的输出

(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)
  )

我得到的第一个函数的输出为：

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

从输出中，我相信该文档已正确编入索引

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 []}}

和nil分别。

我在这里想念什么？

PS：我是clojure和弹性搜索的新手

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

您的代码esd/search也有同样的问题，但除此之外，您应该更改last_name为last-name小写字母"Smith"，以使"smith"一切正常。
