class NumberFilter extends TokenFilter

Recently I wrote a small NumberFilter similar in structure to the
StopFilter except it filters out numeric tokens.  Anyway, here is the
simple source code if you are interested in adding it into the API as it
would seem to be something that needs to be done fairly often ???

class NumberFilter extends TokenFilter
{
	NumberFilter(TokenStream in)
	{
		super(in);
	}
	public Token next() throws IOException
	{
		for(Token token = input.next(); token != null; token = input.next())
		{
			if(Character.isDigit(token.termText().charAt(0))==false)
				return token;
		}
		return null;
	}
}

PATCH: unused code in BooleanScorer.java

Dear developers,

All tests pass here with this change in BooleanScorer.java.
The collectHits method is not used anywhere in the Lucene code
and it's not part of the API defined by Scorer.

Have a nice day,
Paul

Inconsistent behaviour sorting against field with no related documents

           Summary: Inconsistent behaviour sorting against field with no
                    related documents
           Product: Lucene
           Version: CVS Nightly - Specify date in submission
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Search
        AssignedTo: lucene-dev <at> jakarta.apache.org
        ReportedBy: sam <at> redspr.com

In StringSortedHitQueue - generateSortIndex seems to mistake 
the TermEnum having values as indicating that the sort field 
has entries in the index.

In the case where the search has matching results an ArrayIndexOutOfBounds
exception is thrown in sortValue (line 177 StringSortedHitQueue)
as generateSortIndex creates a terms array of zero length and fieldOrder

altering index

Hi, 

I'm working on a project to search for documents on the web. Everything
works fine, but I want to restrict the availability of the documents. When
the user gives it's document to get indexed he can choose a date at which
the document's availability should expire. So I need a field or something
like that in which I can save the date of expiration. Over this field I want
to alter the index. 
I hope I haven't explained my problem to unclear. So, does anybody know any
methods to do this or how I can alter my index the best way?

Would be great, 
thx Amrûn

Re: altering index

Two points if I understand your question:

1) Search scope:
Add your date of expiration in the index and restrict searches on that
date. You can use a date filter, or a ranged query in a field with the
date in a yyyyMMdd format.

2) Document management scope:
When the date expires, you might want to schedule for the document to be
removed from the index.

HTH,
sv

New Sorting Classes

Hello,

I quickly had a look in the new sorting classes and didn't find any information regarding field sorting for
"String" values based on a Locale. Should StringSortedHitQueue.java accept a Locale such that its
ScoreDocLookupComparator.compare() method could sort the values properly for the Locale language.
Or, did I overlook something?

Thanks,
RBP

Re: New Sorting Classes

yes, I think you're right - there should be a way to specify the Locale in
the SortField somehow.

What about something like:

  public SortField (String field, Locale locale, boolean reverse);

Where the given field contains Strings in the given Locale.

This, then, would propagate down to the StringSortedHitQueue, etc.

?
