I have download source ?1.10? from the internet and build it into lib Then I create a project as the helpdoc said I using vc2005(vc8) The source in my test project is as follow??copy from the helpdoc? #include <xapian.h> #include <iostream> using namespace std; int main(int argc, char **argv) { // Simplest possible options parsing: we just require three or more

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

Hello, Been using Xapian and the Java bindings for years, all was working great, and I all of a sudden decided to upgrade to the latest 1.2.12 and use the new java-swig bindings instead of the old hand-crafted JNI which I think have been deprecated now. I'm struggling with the new design of the TermIterator. More specifically, I can't tell when I've reached the end of the list of

Hi all, I've been toying with xapian (mostly using the Python bindings) and I think I've hit a bug in the TermIterator::skip_to() method (or maybe in QuartzAllTermsList::skip_to()). I've attached a c++ source file that demonstrates the issue. In short, if you have a WritableDatabase, ask for the all-terms TermIterator with db.allterms_begin(), and then skip_to() a word that is itself

Morning All, I use scriptindex to build my database and the PHP bindings to pull it all out. Is it possible to have more than one index but select what the bindings search on? So at the moment I index property addresses, I would also like to index property descriptions for more advanced searching but only as an optional extra...probably in an extra search box. Also I would like to analyse the

Hello. Is there any FAST way to get a term from the xapian document by it's position, something like std::string term = Xapian::Document::GetTermByPosition(int position) ? Below i have described a task that i am trying to solve, in case if somebody is interested. ============================================================================ When displaying search results, i would like to

Hi all, I've tried building RPMs for RHEL5 and hit this problem in Search::Xapian: make test fails on test 37: ok 34 - check PositionIterator ok 35 - create TermIterator ok 36 - check TermIterator dubious Test returned status 0 (wstat 11, 0xb) DIED.

Hey, I noticed commit 145503bbe4a5bf702cd13cb2e592111e8d7ca89a (Reimplement Database and WritableDatabase, 2017-10-05) added the phrase: "The terms are returned ascending string order (by byte value)" for termlist_begin. Is that also true for the 1.4 (or even 1.2) series? Also, is allterms_begin also the same w.r.t. ordering? Thanks.

Hi, I would like to create a golang binding for xapian. Has anyone made the necessary swig files for it? If not can someone who has experience with swig offer tips or ready-made files? Cheers, Marius PS1: A sample of how the binding will be used: https://gist.github.com/mtibeica/7d2c680046b4bd0da751#file-quickstart-go PS2: I wrote the nodejs binding for xapian (found on

I'm already retrying the ->get_mset operations; but now I'm wondering where I'd hit DatabaseModifiedErrors while inside a Xapian::MSetIterator loop. I assume ->get_document is a place where it gets thrown; but once a document is retrieved, can iterating through terms in one document (using TermIterator) also throw DB modified? I'm dumping multiple terms per-document to a

I can't quite connect the dots on this, perhaps someone can help. I'm simply trying to create an in-memory database comprising a single document, so that I can run a load of queries against it and see if any of them match the new document (this is to enable users to have 'subscriptions' to saved searches and be alerted every time a new item is published that matches their

Hi, Do the serialise method of Document and Query produce a valid utf8 string? My problem is with the Node.JS binding. I serialise an object, convert the string to a javascript string, convert the javascript string to a std string and then try to unserialise. The error I get from Xapian is "Bad encoded length: no data". Thanks, Marius -------------- next part -------------- An HTML

Hello, I have a problem when trying to define a query and setting for each term its "term frequency" with the classical constructor Xapian::Query<http://xapian.org/docs/apidoc/html/classXapian_1_1Query.html#f396e213df0d8bcffa473a75ebf228d6>(const std::string &tname_,

Hello, Thanks James for the reply. That cleared a few things out. Apologies for replying late because of exams going on. I was going through the previous clustering API to understand how it worked and it seems like the the approach for construction of the termlists which are used for distance metrics use TF-IDF weighting with cosine similarity, which is very similar to the approach I would need

I'm having trouble translating from C++ to perl objects. The TermIterator class looks like to get a set of terms in a document you might have C++ code like: Enquire::TermIterator termIt =enquire->get_matching_terms_begin(id); for(;termIt != enquire->get_matching_terms_end(id);termIt++) { string term = *termIt; } Or something similar. However when I attempt to translate that

One issue left for me to figure out is that in different languages there are different characters and Xapian takes only english characters. Thefore many word entered by users that contains their own language special characters will not return any result. MySQL offers different collations ... Now when I see how much data Xapian can search perhaps I could expand my index spider different European
