我正在运行solr 7.2.1版本，使用SolrCloud和基于示例配置的集合。配置的lucene部分（http://localhost:8983/solr/admin/info/system?wt=yaml）是

solr-spec-version   "7.2.1"
solr-impl-version   "7.2.1 b2b6438b37073bee1fca40374e85bf91aa457c0b - ubuntu - 2018-01-10 00:54:21"
lucene-spec-version "7.2.1"
lucene-impl-version "7.2.1 b2b6438b37073bee1fca40374e85bf91aa457c0b - ubuntu - 2018-01-10 00:48:43"

术语配置（http://localhost:8983/solr/trans/config?wt=yaml）为：

name    "terms"
class   "solr.TermsComponent"

http://localhost:8983/solr/trans/terms?wt=xml会传回：

<lst name="/terms">
  <str name="startup">lazy</str>
  <str name="name">/terms</str>
  <str name="class">solr.SearchHandler</str>
  <lst name="defaults">
    <bool name="terms">true</bool>
    <bool name="distrib">false</bool>
  </lst><arr name="components"><str>terms</str></arr>
</lst>

尽管集合中有1K个文档（http://localhost:8983/solr/trans/query?q=*:*&rows=0，2MB的文本）：

{
  "responseHeader":{
    "zkConnected":true,
    "status":0,
    "QTime":4,
    "params":{
      "q":"*:*",
      "rows":"0"}},
  "response":{"numFound":978,"start":0,"maxScore":1.0,"docs":[]
  }}

我怎样才能看到得到的项（和他们的频率）？
