我正在使用分布式查询来获取记录。维基上的分布式搜索文档说，分布式搜索支持术语向量。但我在查询时遇到错误。不确定我做错了什么。
下面是我使用分布式搜索获取术语向量的查询。
http://localhost:8080/solr/core1/tvrh?q=id:3426545&tv.all=true&f.text.tv.tf_idf=false&f.text.tv.df=false&tv.fl=text&shards=localhost:8080/solr/core1,localhost:8080/solr/core2,localhost:8080/solr/core3&shards.qt=select&debugQuery=on
下面是错误......
