Hello Paul, hello Doug, many thanks for your help !!
@Paul: I didn't try your method, Paul, because I feared that retrieving all hits would not solve my problems, because the number of hits may be many times higher than the 2000 I wanted for my statistics. @Doug: I tried your method which is extremely fast ! The first run is still very slow (many seconds, but this is not a problem for me), measuring the following ones sometimes gives 0ms using currentTimeMillis() !! Now I have one more question: I want to use the TopDocs result TopDocs hits = searcher.search(query, (Filter)null, 2000); as a filter for following queries like DE:Schlüssel limited to the 2000 TopDocs for the query "key" AFAIK, the recommended way for search within a search is: Combine the previous query with the current query using BooleanQuery, wherein the previous query is marked as required. Can this be done in this case ? My query does not contain any information that I want 2000 results as maximum. Note: I do not want to limit the combined query to 2000, but typically I expect fewer results by first restricting the "key" query to 2000 and then looking in the results for DE:"Schlüssel".
