thks but It doesn't work, I tried this
Hits encontrados=searcher.search(buscar,new Sort("DATE"));
and all my documents have a Field.Keyword called DATE.
If i do the search without sort parameter it returns me a lot of
results, but if i do the search with sort parameter it doesn't return
any hits.why?
I thinked that the only thing that I need to use Sort is that the
field was indexed and not tokenized and in my case is a Field type
Keyword.

Just use the Sort option in the searcher

Subject: Hits sorted
Hi everybody, I have a problem when I find all the documents added in
the last days in my index. It works good but I want show this results
sorted. What I have to do?
My code is this:
private RangeQuery findINTODates(int days) {
Term from;
Term to;
Calendar calendar = new GregorianCalendar();
calendar.add(Calendar.DATE,-(days));
SimpleDateFormat originalFormatter = new SimpleDateFormat
("yyyyMMdd");
from = new
Term("DATE",originalFormatter.format(calendar.getTime()));
to = new Term("DATE",originalFormatter.format(new Date()));
RangeQuery lastdays= new RangeQuery(from,to,true);
return lasdays;
}
and I call this
Hits returned=searcher.search(findINTODates(num_days));
What I have to do? I have to use DateFilter or Sort elements ? I don't
know how to work with these classes.
In mMy documents of lucene I added the field Date how a string and not
how a date because it's more easy for add documents to index in my case.
thks for all.
