Re: Hits sorted
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.

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
(MMdd);
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.

Of course you'd have to update your index to store the date in the same format. Miles Barr - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Unexpected analyzer behaviour with special characters
Hi,
I don't understand why my third test fails. If I scape my - delimiter
what I expect is a character behaviour.
Could you clarify me what I'm doing wrong?
public void testStandardAnalyzer() throws Exception {
Analyzer a = new StandardAnalyzer();
assertAnalyzesTo(a, ses1-one3, new String[]{ses1-one3});
assertAnalyzesTo(a, session-one, new String[]{session,one});
assertAnalyzesTo(a, session\\-one, new String[]{session\\-one});
}
Thanking in advance

Re: Unexpected analyzer behaviour with special characters
StandardAnalyzer does not have any escaped-character handling
capability. So the backslash and dash are treated without any
special care in session\-one.
You will need to build your own Analyzer with a custom tokenizer to
handle this type of escaping.

RE: RemoteSearchable woes
The system I'm working on requires that I also need to use a custom hit collector. I'm not using the RemoteSearchable. Instead, I'm just binding an object called SearcherImpl that contains an IndexSearcher and a getResults() method that uses the custom hit collector.

I'm on v1.4.3 and am using it just fine, until I need to: 1) use a custom sort, or 2) use something that extends HitCollector I've got an idea as to the reasons why (serialization and remoteness), but how do I get around these?

Re: docMap array in SegmentMergeInfo
Hi Yonik, Your patch has corrected the thread thrashing problem on multi-cpu systems. I've tested it with both 1.4.3 and 1.9. I haven't seen 100X performance gain, but that's because I'm caching QueryFilters and Lucene is caching the sort fields. Thanks for the fast response! btw, I had previously tried Chris's fix (replace synchronized method with snapshot reference), but I was getting errors trying to fetch stored fields from the Hits. I didn't chase it down, but the errors went away when I reverted that specific patch.

Re: Do you believe in Clause sanity?
Oops, I'm confusing libraries. I meant I want to remove a Nutch Clause from a Nutch Query. --Andy On Oct 13, 2005, at 4:45 PM, Andy Lee wrote: The API for BooleanQuery only seems to allow adding clauses. The nearest way I can see to *remove* a clause is by laboriously constructing a new BooleanQuery (assuming you aren't absolutely tied to the original instance) and adding all the clauses from the original query except the one you're removing. And *that's* rather cumbersome because you can't actually add a clause; you have to use one of the addRequired-/addProhibited- methods -- and they take arrays of String rather than the array of Term that you can get from a Clause. It seems reasonable to me to want to remove clauses from a query. Is there some reasonable way of doing this that I'm missing? --Andy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
