在Lucene/Lucene.net搜索中,如何计算每个文档的点击次数？

Question

搜索大量文档时,我可以轻松找到符合我搜索条件的文档数量:

Hits hits = Searcher.Search(query);
int DocumentCount = hits.Length();

如何确定文档中的总点击数？例如,假设我搜索"congress",我会收到2份文件.如何获得每个文档中"会议"的次数？例如,假设"会议"在文档#1中出现2次,在文档#2中出现3次.我要找的结果是5.

这是Lucene Java,但应该适用于Lucene.NET:

List docIds = // doc ids for documents that matched the query, 
              // sorted in ascending order 

int totalFreq = 0;
TermDocs termDocs = reader.termDocs();
termDocs.seek(new Term("my_field", "congress"));
for (int id : docIds) {
    termDocs.skipTo(id);
    totalFreq += termDocs.freq();
}
