如何使用termVectorComponent創建solr中的標籤雲

Question

我正嘗試使用solr v2.2創建標籤雲。我已經讀夠了，但在網上找不到新手的例子。我想要做的是;

我有一個字段;

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

我想要得到單詞的tf和idf值。

我到目前爲止所做的是;

當我輸入下面的查詢

本地主機/ Solr的/ tvrh/Q =的queryString &版= 2.2 &縮進=上& tv.tf_idf =真

我得到一個基於文件的效果一樣？;

<lst name="doc-40797">

如何獲得全部結果，而不是基於文檔？或者是否有更好的方法來獲得tf和idf值與termVectorComponent查詢solr分開？

在此先感謝！

Answer 1

爲了獲得所有文件;

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. 
}
