我正在尝试使用 solr v2.2 创建标签云。我已经阅读了足够多的内容，但我在网上找不到任何新手示例。我想做的是；

我有一个领域；

<field name="content" stored="true" indexed="true" multiValued="true" termVectors="true"/>

我正在尝试获取单词的 tf 和 idf 值。

我到目前为止所做的是；

当我输入以下查询时

localhost/solr/tvrh/?q=queryString&version=2.2&indent=on&tv.tf_idf=true

我根据以下文件获得结果；

<lst name="doc-40797">
<str name="uniqueKey">test20508</str>

我怎样才能得到总的结果，而不是基于文件？或者有没有更好的方法通过 termVectorComponent 查询在 solr 中分别获取 tf 和 idf 值？

提前致谢！

为了获得所有文件；

NamedList<Object> solrResponse = server.request(new QueryRequest(queryString));
NamedList<Object> namedList = (NamedList<Object>) solrResponse.get("termVectors");
for (int i = 0; i < namedList.size(); i +=2) {
                    Object val = namedList.getVal(i);
                    System.out.println(val.toString());//I chose to print them.
}
