How to count I/O consuming in OProfile while profiling xapian

Hi,


I have tried to profile xapian, according to the Wiki: http://trac.xapian.org/wiki/ProfilingXapian, we can profiling I/O bound cases with oprofile, but from many other articles, it seems that we can not do it in oprofile.

I have followed that wiki page, installed oprofile and libc6-dbg, but it doesn't work, only CPU bound functions are counted.

Anyone know how to count I/O cost in oprofile? Many thanks!

Best Regards!

Looking for a project

Hi ml,

I'm an senior year CS student working in information retrieval. I was looking for a project to do (preferably related to information retrieval). Can someone guide me and sort of mentor me part time?

Thanks,
Swair.

How to enable stemming with default_op set to OP_NEAR

Hi All,

I know that from version 1.2.6, if default_op is OP_NEAR or OP_PHRASE then stemming of the terms is disabled, since positional information isn't indexed for stemmed terms by default. However, I would like to try using OP_NEAR as default_op with stemming because I think the near operator is somehow different from exact phrase. Then I wanna see how the search results looks with this setting compared to those with OP_AND as default_op. However, even I managed to index stemmed terms with position information I couldn't find where to make changes to enable stemming in queryparser. I checked with queryparser.cc and queryparser_internal.cc, but haven't find the exact piece of codes which disabled stemming when default_op is OP_NEAR. So I guess maybe someone here could offer some he lp, and I really appreciate your time!

Thanks,
Shen

GSoC Final Evaluations

The cut-off date for work which can be included for consideration when
the mentors fill in the final evaluations for Google is this coming
Monday - 2011-08-22 at 19:00 UTC.

It is totally OK to continue to work on your project after this date,
and indeed we'd like to encourage you to do so!  But Google ask us to
only consider work done before this point for the purposes of the final
evaluation.

There's also a survey for students to fill out, which you should be
able to find at:

http://www.google-melange.com/gsoc/dashboard/google/gsoc2011

Google will also want "code samples" uploading in the next week or two,
but I don't know exactly what the details are yet for this year, but in
past years, something like a diff between trunk and your tree has been
suitable.  This should be done for the state of your tree at or before
the cut-off date.  But for now, just wait for more details of this.

Cheers,
    Olly

Interest in developement as a student

Hello.


I am an undergraduate student studying computer science and I am interested in working in your Open Source projects.
I read about you from TeachingOpenSource.org.

I am, however, new to Open Source project development thus I am seeking a mentor and an opportunity to present my skills and make valuable contributions to your projects.

Thanking you.

How to add support of Chinese & Japanese

I wonder anyone has successful experience on supporting Chinese and Japanese?

 

Where did you make change to support index creation, where did you change the code to support search?

 

did you be able to support Synonymy? where to support this?

 

did you support auto completion(user enter partial of a word, the search engine find the complete words)?

 

thanks for any info sharing,

 

Bruce
