Hi all, Most of our queries are very simple, of the type:
Query query = new PrefixQuery(new Term(LABEL_FIELD, prefix)); Hits hits = searcher.search(query, new Sort(new SortField(LABEL_FIELD))) Which sometimes result in 10, 20, sometimes 40 thousand hits. I get good performance if hits.length is 20.000 or less (less than 0.5 seconds). I However, if it is 40.000 or more, querying takes over a second, up to 2.5 seconds. Point in check here is that this solution is not scaling. Any ideas I can try? I already exhausted the ideas from http://wiki.apache.org/lucene -java/ImproveSearchingSpeed I was reading about TopDocs and TopFieldDocs. Is this search method (using TopDocs) preferred over Hits? Also, there's no constructor for them without a Filter, can I just pass null? Is it possible to pre-sort the index, so I don't have to every time I perform a query? Any other ideas? Thanks, Andre
