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。
我想在下面获取tf和idf值;

到现在;
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,我想我将需要QueryResponse对象,我认为这是事实。但是我不知道接下来使用
solrj
获得那些tf-idf值的方法是什么。谢谢
最佳答案
您几乎在那里:
QueryResponse qr = server.query(query);
TermsResponse resp = qr.getTermsResponse();
TermsResponse对象包含术语向量分量输出。不知道它是否包含所有信息。
