此查询在solR中出现500错误：
msg : "Error from server at http://localhost:8983/solr/core_replica1: Exception during facet.field: text"
trace : "org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException:
Error from server at http://localhost:8983/solr/core_replica1: Exception during facet.field: text\n\tat
我注意到，如果将参数“facet.limit”设置为小于5，则可以正常工作，否则不会。这是来自SolR的堆栈：

你知道为什么会发生这种错误吗？
我使用Solr 6.6.0。 我请求的字段是org.apache.solr.schema.TextField：
索引|标记化|存储| TermVector存储|使用TermVector存储偏移量|存储位置使用TermVector属性和shema
谢谢！
