Hello, I'm trying to find the number of documents for a specific term to create text statistics. I'm not interested in ordering the results or even recieving the first result. I just need the number of results.
Currently, I'm trying to do this by using the lucene searcher class: IndexSearcher searcher = new IndexSearcher(reader); String queryString = fieldname+":" + term; QueryParser parser = new QueryParser(fieldname, new GermanAnalyzer()); TopDocs d = searcher.search(parser.parse(queryString), filter, 1); int count = d.totalHits; The problem is, that there is a large index (optimized) with > 8 mio. entries. One search could return a large number of search results (> 1 mio). Currently these search tasks take more than 15 secunds. The question is: is there any way to get the number of search results faster? I think, that it could be optimized by not using a Weight object (order is not interesting), but I haven't seen a way to do this. I hope, someone has already solved this problem.
