Clojure彈性搜索API Elastisch沒有返回結果或文件

Question

我嘗試了clojure彈性搜索API Elastisch。

我是按照文檔中提供的演示代碼 我收到文件/索引創建的輸出以下代碼

(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) 
) 

我收到輸出的第一個功能爲：

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

從輸出我相信該文檔正在索引

問題是，第二個和第三個函數返回：

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

和nil。

我在這裏錯過了什麼？

P.S：我是新來的Clojure和彈性搜索

Answer 1

esd/get失敗，因爲你映射類型爲:person沒有"person"（關鍵字與字符串）。

您的代碼esd/search有同樣的問題，但除此之外，你應該改變last_name到last-name和下殼"Smith"到"smith"一切都應該工作。
