Hi, While porting the unit tests from perl for the node binding I noticed a test failed. I basically create a document, add a few terms, add the document to a database and then call doc->termlist_begin().get_termfreq(). This throws "Can't get term frequency from a document termlist which is not associated with a database." What I think this means is that I can not call

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

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 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

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.

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

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

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, 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_,

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

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

Hey Guys, Just making some enquieres for a project i'm goign to be starting using xapian. When searching over a indexed document will i be able to get a list of hits, how many hits and the location fo the hits. I will have boolean searches like eg ("Mysql" AND ("Linux" OR "Windows")) On each hit i will be wanting teh location of the word found and how many

Dear all, I try to use the xapian-compact tool to merge several databases. I need to keep the document ID. The problem is that xapian-compact is not able to merge databases because of overlapping "doc ID range". Nevertheless, in my case, a doc ID is always used for one and only one database. Is there a (other) clever way to simply and quickly merge databases ? Regards 2011/3/7

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) ?

I have a xapian-daemon, which can be queried via http. A background-process generated every hour one new index and then remove and create a new symlink to the current database. /path/to/index/20120419010000 /path/to/index/20120419020000 /path/to/index/20120419030000 /path/to/index/default => /path/to/index/20120419030000 So the daemon only check the mtime of /path/to/index/default/iamchert
