java - 如何使用 solrj 获取 solr termVectorComponent 结果

Question

我正在尝试编写此查询；

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

使用 solrj。

我想获取下面的 tf 和 idf 值；

到目前为止；

        SolrQuery query = new SolrQuery(queryString);
        query.setQueryType("/tvrh");
        query.setParam("tv.tf_idf", true);
        QueryResponse response = server.query(query);

我已经编写了查询，我想我需要 QueryResponse 对象，我认为这是真的。但我不知道接下来如何使用 solrj 获取这些 tf-idf 值。

谢谢

你就快到了:

QueryResponse qr = server.query(query);
TermsResponse resp = qr.getTermsResponse();

TermsResponse对象包含项 vector 分量输出。但不确定它是否包含所有信息。
