Hi, I'm Ayush an undergraduate Computer Science student from Thapar university, India. I was fiddling with xapian since the morning and trying to understand the code and internals of Xapian. I tried implementing the bite sized project idea posted here: https://trac.xapian.org/wiki/ProjectIdeas#AddnewOmegaScriptcommandtodoasubstringsearch but could not understand what needs to be returned when

Google's "Summer of Code" is on again. If you're not familiar with GSoC, see: http://code.google.com/soc/ We had a brief discussion on IRC, and we have enough potential mentors to make it worth applying again. Org applications are open Feb 3rd-14th. Accepted orgs are announced on Feb 24th, and students can apply between March 10th and 21st, but the keen ones have already

Hello folks- I have an issue with my Xapian index, and I am hoping someone can help me out with some ideas. I am running Xapian on Debian Squeeze as part of an openPLM installation. It is a django application that uses Postgresql as the database, and Haystack as the search engine. A couple of weeks ago, I misconfigured a crontab, and it made a recursive backup that filled up the hard drive

Hello James, I am working on breaking down Features into sub-classes. Should each of the features get their own sub-class, or should the grouping be done according to type? i.e. query-document pair dependent, query-dependent and document dependent sub-classes. Using this approach makes more sense if we plan to add support for user to include query-dependent and document-dependent features in

Hello, I'm Ayush from New Delhi, India. I am interested in Letor Stabilisation project for GSoC. I have a good background in machine learning. Sorry for getting in so late, university exams were holding me back. I'll try to cover as much as I can in the coming week. I am following the plan of attack suggested on the project page. Following are the things that I have completed: 1.

Hello, I am trying to rebuild an index of 2+ million documents and have not been successful. I am running Python 2.7 Django 1.7 Haystack 2.1.1 Xapian 1.2.21 The index rebuild command I’m using is: django-admin.py rebuild_index --noinput --batch-size=100000 The rebuild completes but an immediate xapian-check returns this error: xapian-check ./archive_index record: baseB blocksize=8K

Hello, I wanted to decide the dataset that should be used for Letor stabilisation project. I think 2009 INEX Wikipedia Collection <http://www.mpi-inf.mpg.de/departments/databases-and-information-systems/software/inex/> should work fine. It's a collection of 2,666,190 XML articles, 115 topics <http://inex.mmci.uni-saarland.de/protected/adhoc/2009-topics.zip>, 50,275 qrel

Hello, I applied to letor stabilisation project for gsoc. I'd like to use coming weeks to improve the workability of xapian-letor. For that, I'm planning to refactor code in current master and begin writing some tests for it. Before adding tests, I think it would be better if xapian-letor could be made consistent with how xapian-core is written. For that, I'd first like to

Hello everyone, I have completed introducing some code from v-hasu's branch into mine, mainly for Features, FeatureVector and FeatureManager classes. I have pushed the changes to https://github.com/ayshtmr/xapian/tree/letor-update. I am now proceeding to write unit tests for feature modules. There are a few things that I wanted to clarify: 1. I have introduced a lot of code in a single

Hi Olly, Thanks for the detailed response. I hadn’t realized there was a new xapian haystack backend. I’m going to try that but I have some upgrades to do first. Django 1.8, etc. Thanks, Ryan > On Feb 28, 2017, at 3:40 PM, Olly Betts <olly at survex.com> wrote: > > On Mon, Feb 27, 2017 at 10:29:46AM -0800, Ryan Cross wrote: >> I am trying to rebuild an index of 2+

Hello everyone, My name is Ayush Tomar. I'll be working on Learning to Rank stabilisation project over the summers. Here are a few things that I plan to do in coming few days: 1. Revise the timeline. There are some portions that I had kept for the first and second week of coding which have already been done (except writing tests). So, I'd like to adjust the timeline according to it. 2.

Hi, I'm the current developer of Xapian-Haystack, and I'm glad to announce that we've been finally able to install and pass all the tests of Xapian-Haystack with Xapian 1.3.3 in both Python 2 and 3, which means that Xapian-Haystack now supports Python 3. This naturally would not be possible without your efforts to push Xapian bindings to Python 3, and I thank you for that. Here I

Hello everyone! I'm Ayush Tomar, junior undergrad in Computer Science from New Delhi, India. I love C++ coding and working on machine learning and information retrieval project. I was exploring the GSoC ideas for Xapian and the project on "Adding Weighting Schemes" looked really interesting to me. I wanted to work on text mining/IR this summer and this idea seems perfect! I have

Hello, Do xapian has analyzer like EdgeNGram to use it for autocomplete. I am trying to use the auto completion using xapian. For example: e ex exa exam example etc.. so that we can get it. I tried to use using the Partial flag but it dose not work Xapian::Query query = parser.parse_query("m*",parser.FLAG_PARTIAL); Do you have any example or any tutorial is appreciated. --Naveen.

Hello James, Parth, Following our discussion on IRC and on code review, the way FeatureVector class works needs some discussion. Presently, the FeatureVector class is defined as follows, with a fixed number of feature count (19): class FeatureVector::Internal : public Xapian::Internal::intrusive_base{ friend class FeatureVector; double label; double score;
