有錯誤，同時在solr中聲明多個實體

Question

我剛開始學習solr。我已經安裝了apache tomcat服務器和solr 3.5。我已成功配置solr以便從Oracle數據庫搜索一個實體的數據。我有問題，當我在數據-config.xml中增加了兩個實體和Solr的schema.xml.I添加字段配置我的數據-config.xml中像這樣...

和我配置我的schema.xml中像這樣...

    <uniqueKey>projects_id</uniqueKey>

</schema> 

和我的solrconfig.xml中是...

<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler"> 
     <lst name="defaults"> 
      <str name="config">/opt/solr/core0/conf/data-config.xml</str> 
     </lst> 
    </requestHandler> 

現在，當我運行一個完整的導入命令我收到以下錯誤。 。

solr無法讀取第二個實體的任何字段。 任何人都可以幫我解決這個問題..？ 請告訴我我在配置data-config.xml或schema.xml或兩個文件時犯了什麼錯誤..

Answer 1

雖然從堆棧跟蹤看起來像您的計劃文檔之一缺少所需的plans_applied字段中的值，我認爲首先需要注意的是數據不應該在Solr中規範化。它應該在輸入索引之前變平。

因此，您應該在這兩個表之間創建一個連接（直接在data-config.xml中，而不是您的查詢），以便每個生成的（連接）錶行成爲Solr文件。

這樣，當您想要獲取有關單個項目的所有數據時，它將全部位於單個文檔中 - 無需爲此類用例進行連接。

在Solr中，您應該擁抱冗餘，而不是關係和約束。

有意義嗎？
