The reason that I want to limit returned result is that I do not want to get out of memory problem. I index lucene with 3 million documents. Sometimes, searching will return millions of fields back to me. I just want to get the first 100, for example , to show them to user. Even, I use search(query,filter,topDocs), I believe it still return all results back. So how could I limit the lucene returning?
