Google results page will show these info:About 439,000,000 results (0.21 seconds)
so i think any application will show the total matched results to the user.Lucene need to think about implement this function?haha
thanks Ian. I will search the mail archive.

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.

thanks.Ian.
The number of the results matched the query is the return value: TopDocs search(Query query, int n) ,the n arg pass to the method means that lucene just
search the top n results.But i want to get the matched number that is the whole index returned not the n i pass into the TopDocs search(Query query, int n) .Hope i clear my issue.
thanks again
