similar to: Indexing more than 15 billion documents

Hello all. I need to redefine a docid type (and all dependent types) like this: typedef unsigned long long docid; I think it would be enough to edit "include/xapian/types.h", but it isn't so. 1) I've added : string om_tostring(unsigned long long val) { CONVERT_TO_STRING("%llu") } in common/utils.{h,cc} 2) In include/enquire.h (line 438) I've found the

Hello, I'm using Xapian 1.0.2 (flint) and matching Search::Xapian. I'm getting: terminate called after throwing an instance of 'Xapian::DocNotFoundError', which dumps core. at first it was after adding my 2nd document (to an empty db, although I don't know if that has any bearing) to the database with a replace_document() call. I shifted the first document off the

Hello, i switched from one big index to a stub file with many indexes and running into a problem. i have a tool to fetch a random document via: get_doccount random id up to get_doccount get_document with that id after changing to stub file this failes. Is there a nice way to get a random document from a stub file? ?MfG? Felix Ostmann

Hi, all: I am confused with the concept of colletion_freq There's no informations about it on http://xapian.org/docs/glossary.html What does it means?

Hi, is there a way to get the number of all possible matches for a specific query? Some api call like Xapian::doccount Xapian::Enquire::get_number_of_matches(); Best wishes Wilm

The way I was thinking of performing reranking with updated weights was to add a class MSetRanker (basically containing a

The series introduces auto-generation of the type definitions used in the libxl interface followed by auto-generation of a destructor function for each type. In the future it may be possible to use the related data structures for other purposes, for example auto-generation of the functions to marshal between C and language binding data types. tools/_libxl_types.h should be identical both before

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, -- Yann

Sir, I am a 4th yr undergraduate student pursuing my BTech in CSE at IIIT Hyderbad, India. I am interested in applying for Xapian in Gsoc 2014. I had gone through this year's idea page and interested in applying for 'posting list encoding improvements' project. I am good at C/C++,python; which is one of the requirement. I had done gone through the information Retrieval and

The Database object itself effectively does (it works in a snapshot of the state of the database when you open it, or last called reopen() which

In other words, is it possible to avoid duplicates if new documents are inserted into the DB by another process in-between ->get_mset calls when reusing Xapian::Enquire objects? I do some expensive processing on each mset window, so I always limit the results to limit heap usage even if I'm planning on going through a big chunk of the DB: $mset = $enq->get_mset(0, 1000);

I've looked over the docs on remote backends, the protocol, and a bit of the c++ for doing distributed and remote searches. I've got a couple of questions: * The remote protocol is usable only as a Database, not as a WriteableDatabase -- is this correct? So, if I don't want my application to have a copy of the database on the same machine I'll need to write an indexer daemon on

Changes since last time: - split auto-generated code in to c and h files - un-break the build system - fix ocaml binding due to libxl API change - lot''s of tidy-ups too numerous to mention Please consider and apply :) -----8<--------------------------------------------------------------- Introduce python binding for libxl. The binding is not yet complete but list_domains,

Hello everybody, I am 20 days with the same item and I can't configure it. I want to know if someone has the Billion ISDN card on a Debian Etch, because everybody tells me to do that, then the other one but no one has the same configuration. If some one has the same configuration (Billion + Debian Etc), can you help? What packages install and what steps continue. Thanks to all and have a

I'm looking at experimenting with asterisk with an ISDN BRI and ISDN phones (since I have these already). I saw that the Billion card was cheap and could be used in either TE or NT modes. I have the following question which I couldn't answer by reading through the manual. Maybe someone has experience of using this card and can help me out. when using in NT mode does the card require
