Test for the end of PostingIterator in perl?
...with Search::Xapian in perl version 1.2, but now with
xapian-bindings-1.4.4 it does not seem to. How are you supposed to tell
when you have reached the end of a postlist?
The above code now appears to segfault at get_docid, presumably because
we went over the end of the list.
Thanks,

...gt;index_text($txt,$weight);
If I wanted to allow the user the option of searching either in
recency-weighted mode or not, I could index each document into 2
different databases, one with and one without.
This avoids having to mess with subclassing PostingSource and C++ and
all that.

...the score by which I sort
the results. I may be able to stumble around and figure this out, but I
wonder if any current xapian users have done something like this and how
did it work out?
We are a perl shop, but I guess I will need to figure out some C++ in
order to do this?

perl bindings to Xapian::Query
...#39; at
/usr/local/lib/perl5/site_perl/Xapian.pm line 1282.
I see in Xapian.pm where Xapian::Query attempts to call
Xapianc::new_Query . Is there some other way I am supposed to do this?
I should say that I am using xapian-bindings-1.4.4 which I compiled and
installed myself.
Thanks,

Given a document, how do you get its ID? (perl bindings)
I am writing an indexer that will crawl our web site. Following the
recommendation here:
https://trac.xapian.org/wiki/FAQ/UniqueIds
I'm using the URL as the unique ID for each document. I see how to get a
document from the xapian database if I know its URL, but what I need is
also to be able to find out the URL from the document. Does this mean I
need to store the URL in a value in

I think your issue here is that $filterepoch is a number rather than

Network booting FreeBSD with gpxelinx almost works
...Again, changing gpxelinux to pxelinux does cure the problem.
I have to apologize for posting this in a way that breaks threading, but the
replies never got to my mailbox, and I had to synthesize this message from the
syslinux archive.

Weighting the author of a doc when that term can also appear as a frequent term in other docs
We have a corpus of academic papers. Sometimes it happens that there is
an academic controversy and one paper is a response or rebuttal to
another paper. The name of the author of the first paper may appear many
times in the second paper. So in light of this, how should we set our
weight on the author field?
Here is an example:

(2.2.5) Does AUTO PRINTER DRIVERS work - definitive statement please
Hi, could someone who is close to the Samba development
make a comment about the automatic printer drivers features in Samba 2.2.5
I've been trying to get this working unsuccessfully, and have seen many
messages posted from people having trouble with this feature.
Not sure if this is an unnusual number of people with problems, but
it seems like it ( I could be too close to the problem to see
