Subject Re: How to search documents taking in account the dates ???
Date Thu, 18 Dec 2008 13:11:10 GMT
What I am doing is this:
<code>
            Sort sort = new Sort();
            sort.setSort("year", true);
            hits = searcher.search(pquery,sort);
</code>

How I must put my code to sort first by date an then by score ???
Greetings
Ariel
