無法設置導出處理程序的Solr

我已經在這裏跟着指示爲Solr的設置導出處理程序，我試圖檢索數據時有問題：無法設置導出處理程序的Solr

我已經設置了solrconfig Exporting Result Sets 所以我已經加入：.XML如在該指令中提到

<requestHandler name="/export" class="solr.SearchHandler"> 
    <lst name="invariants"> 
    <str name="rq">{!xport}</str> 
    <str name="wt">xsort</str> 
    <str name="distrib">false</str> 
    </lst> 
    <arr name="components"> 
    <str>query</str> 
    </arr> 
</requestHandler>

但是當我使用下面的查詢，我得到上述錯誤：

http://big-d-cluster:8983/solr/trading/export?q=*%3A*&fl=id&sort=tradeTimestamp+desc

任何想法可能導致這種情況？

我使用的是SolR 4.10，我沒有使用Sorj所以它應該可以工作，所以我沒有複製：Solrj export或Issue because user was not using SolR 4.10+。

我發現如果Solr索引沒有數據，您會收到上述錯誤。我填充它，它工作。
