Multiple field searching

2002-03-19 Thread Tate Jones 

hi,

I am trying to search across multiple fields using the following query

+keyword:computers +subject:News content:xml
or
+(keyword:{computers}) +(subject:{News}) content:xml

i have added the fields to the document correctly. 

Have also tried using the MutipleFieldQueryParser without success.

The only query that works is, which is not correct as they are OR's
keyword:computers subject:IT content:xml

Is anyone having the same problems

Thanks in advance
Tate

Tate,

The correct syntax is something like +(keyword:computers) -(subject:News).

HTH.

Maybe it would be helpful to add parse(String[] query, String[] fields,
Analyzer analyzer) methods into MultiFieldQueryParser? What do you think
Otis?

I'm using MultiTermQueryParser and it works for me.

 DateFilter: call enum.next() first

DateFilter.java has changed since the report, but I think I found the
piece of code that you were referring to.
After looking at DateFilter, TermEnum, and FilteredTermEnum it seems to
me that next() does not need to be called first.  This is not
java.util.Enumeration enum, it is TermEnum's enum.
Also, if you look at methods next() and term() in FilteredTermEnum
you'll see that term() does need to be called first, otherwise the
first term would get skipped.
I'm not very familiar with this code, but this is what it seems like
from looking at it for 7:32 minutes.

Hello,

 SegmentTermEnum.clone(), term == null

http://sourceforge.net/tracker/index.php?func=detailaid=451315group_id=3922;
 atid=103922

Aha, this was a bug, indeed, but it looks like this bug has been fixed
about 6 months ago:

revision 1.2
date: 2001/10/11 15:14:14;  author: scottganyo;  state: Exp;  lines: +1

Fix NullPointerException in clone() method when the Term is null.

Re: Lucene Bugs

2002-03-19 Thread Otis Gospodnetic 

Hello,
Has anyone else observed this behaviour?

 Wrong ordering from Document.fields()

http://sourceforge.net/tracker/index.php?func=detailaid=451317group_id=3922;
 atid=103922

It looks like java.util.Enumeration is used to store the fields, so if
Enumeration guarantees order than this should, too.
Could you please provide a self-contained test case that I can just put
somewhere, compile, and run?
I can't compile the snippet in the above bug report.

 No software is bug free; I just want to help make Lucene better.  If 
 I can be of any help, please ask.

Thanks!
Otis
