Writing a MatchDecider and exposing it to PHP
I would like to write a MatchDecider in C++ and expose it to PHP.
I'm able to compile a simple extension and use SWIG to expose a simple
function to PHP, but I can't seem to hit upon the right incantation to
expose my MatchDecider class.
I have a header file declaring my decider, MyDecider.h
#ifndef _INC_MYDECIDER_H
#define?_INC_MYDECIDER_H
#include <xapian/enquire.h>

Remove
Hello,
I would like to remove some files which have the extension .test for
example (data1.test, data2.test ....).
Is there another solution to remove them instead of doing it one by one
?
Thanks for your help,
St?phanie Langevin

Segmentation fault in MSetIterator get_weight
Hi,
I'm using xapian with c# and mono and i'm having a segfault in get_weight.
When i print the index variable, the value is clearly too high.
I think something write over it. Do you have any idea on how i could
trace the beginning of the segmentation fault ?
Thanks,

Connecting to a remote database
Hi,
I''m having trouble connecting to a remote database (mysql). I know that
my connection settings are correct, since I have a php app that is

Are there any settings besides the following that I need in my database

R and Browninan Motion/ Langevin Equation package
Hi,
I'm writing a short course tutorial to Browninan Motion/ Langevin Equation.
At the end of the theory section I wanted to add a short GNU R example, so the students can play a little around.
I already looked in the MASS book (by Venables and Ripley) but I couldn't find any Brownian Motion/ Langevin Equation package.
Are there any good packages or tutorials available which cover R and

simulating from Langevin distributions
Dear all,
I have been looking for a while for ways to simulate from Langevin distributions and I thought I would ask here. I am ok with finding an algorithmic reference, though of course, a R package would be stupendous!
Btw, just to clarify, the Langevin distribution with (mu, K), where mu is a vector and K>0 the concentration parameter is defined to be:
f(x) = exp(K*mu'x) / const where

ExpandDecider and MatchDecider operator() return type
Currently ExpandDecider::operator() and MatchDecider::operator() return
`int' for no very good reason that I can see. It would be more natural to
return `bool', since these classes are making a "yes/no" decision about
whether to include a term in an ESet or a document in an MSet.
The problem is that this can't be done without breaking existing user
code which defines

PHP MatchDecider in 1.2.0
Good afternoon
I would like to ask if is possible in new version of Xapian some kind of
subclasing MatchDecider in PHP. I am developing application where is
very complex permission management. so it cannot be stored in fultext
database. MatchDeciders are perfect for this purpose. But I dont know if
is possible to use them in PHP even if SWIG now supports directors.

How to enhance the query performance for large boolean attribute
Hi all,
I am a new user to Xapian, and now we met such problem. In our case, a document has many attributes which is boolean value, for example( A, B, C ) , and our search query will use certain filter logic ( A == true and B == false ..) to combine with other search logic.
We use MatchDecider to implement the filter logic, and now we met some performance problem, because our self-defined

Enquire::get_mset() "first" and MatchDecider
Hello,
This is a somewhat idle question about Enquire::get_mset(), possibly based
on wrong assumptions on how Xapian works, but I would be grateful if
someone satisfied my curiosity.

How to get the serialise score returned in Xapian::KeyMaker->operator().
HI, all,
I am a user of Xapian, and now I have a problem in using it.
After using boolean terms to get some candidates of documents (still too much), we want sorted them by self-defined function which is used in Xapian::KeyMaker->operator(). But how can I get the serialise score in Xapian::MSetIterator object.
c++ code likes this:

Does xapian support attribute search & faceted search?
Can I use xapian for a search like:
'title' has the phrase "dinner jacket" AND 'color' == BLACK AND 'state' == MA AND 'size' == XL
What about faceted search?
Thanks

I try to use XapianMatchDecider to filtering results, but the code :

issues compiling omega
James,
That was exactly the issue. libmagic.dll.a was in /lib under cygwin. Adding
a -L/lib took care of this. This was also an issue with -lpcre, which
adding -L/lib fixed as well. Of course, I'm now running up against
something else. from make

correlated random effects in GLMMGibbs ?
Dear R-users,
I wondered if anyone has extended GLMMGibbs to include correlated
random effects, and if so, whether they would be willing to let me
use their code?
Jonathan Myles has no plans to extend glmm in this manner within the
foreseeable future.
With thanks,
Patty

Status of the java-swig bindings?
I just get the latest version of Xapian 1.2.2 and see that the Java bindings
still aren't in a package.
Do these work? I am trying to hack them into a package but I can't find
where the actual swig -java command is being executed from to add the
-package command.
Any ideas?

[Omega] Filtering on time instead of date
Hi,
Currently Omega/scriptindex supports filtering by date. For example, all
dates between START and END. Would it be possible to extend this
behaviour to include the time?
We have documents which expire. In order to filter out 'old' articles,
we would like to check if the document date is between START=NOW and
END=MAXINT.
Best regards,
Eric
