Question

我已按照此处的说明为Solr设置导出处理程序，并且在尝试检索数据时遇到问题：

Java.io.IOException: org.apache.solr.search.SyntaxError: xport RankQuery is required for xsort: rq={!xport}

... 26 more

我已按照此说明中的说明设置了solrconfig.xml： Exporting Result Sets 所以我补充道：

<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>

但是当我使用以下查询时，我得到上述错误：

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

知道可能导致这种情况的原因吗？

我正在使用SolR 4.10，我没有使用Sorj所以它应该有用，所以我不是重复：Solrj export或Issue because user was not using SolR 4.10+。

我发现如果Solr索引没有数据，则会收到上述错误。我填充它，它工作。
