Solr 4.x提供了一個實時獲取功能。爲此，它寫入一個更新日誌，它需要定義一個_version字段。

在<fields> tag in schema.xml

<field name="_version_" type="long" indexed="true" stored="true"/>

添加這或者從您的solrconfig.xml中

<requestHandler name="/get" class="solr.RealTimeGetHandler"> 
    <lst name="defaults"> 
     <str name="omitHeader">true</str> 
     <str name="wt">json</str> 
     <str name="indent">true</str> 
    </lst> 
    </requestHandler>

註釋掉該記住，如果你註釋掉/ get請求處理，你不會得到實時獲取也錯過了樂觀併發（在這裏解釋 - http://yonik.com/solr/optimistic-concurrency/）

不知道這是否特定使用太陽黑子，但[字段定義]（https://github.com/sunspot/sunspot/blob/master/sunspot_solr/solr/solr/conf/schema.xml#L241）在使用它時有點不同：' –

正確的行註釋掉，以解決這個問題是： <updateLog> <str name="dir">${solr.ulog.dir:}</str> </updateLog>

P.S. 我知道這是舊的，但仍然進入谷歌搜索的前10名。
