Hello, lucene-user.
I have index with many documents, more than 40 Mil.
Each document has DateField (It is time stamp of document)
I need the most recent results only. I use single instance of IndexSearcher.
When I perform sorted search on this index:
Sort sort = new Sort();
sort.setSort( new SortField[] { new SortField ("modified",
SortField.STRING, true) } );
Hits hits =
searcher.search(QueryParser.parse("good", "content",
StandardAnalyzer()), sort);
then search speed is not good.
Today I have tried search without "sort by modified", but with sort by
Relevance. Speed was much better!
I think that Sort by DateField is very slow. Maybe I do something
wrong about this kind of sorted search? Can you give me advices about
this?
Thanks.
Yura Smolsky.
