Google results page will show these info:About 439,000,000 results (0.21 seconds)

I will search the mail archive. 2011-09-21 janwen | China website : http://www.qianpin.com/ 发件人: Ian Lea <ian....@gmail.com> 发送时间: 2011-09-21 16:27 主 题: Re: Re: search match documents and pagination in lucene3.x 收件人: java-user@lucene.apache.org The n in search(Query query, int n) specifies the number of hits (docs) you want returned. There is no point in lucene accumulating 10,000 if you only want 10 for the first page. TopDocs.totalHits tells you the total number of hits for the query. If you actually want all the hits, see the thread from a couple of days ago about that. -- Ian.
