similar to: docid type redifine

Hi, Sorry to follow up on an old thread, but I am wondering if there has been any work done on, or interest in, increasing the maximum document id beyond a 32bit limit?

Dear, guys: I am a beginner of Xapian, when reading the documents, I encountered follow questions. (1) I see the Xapian::Document has a method void add_value (Xapian::valueno valueno, const std::string &value) What's the purpose of this method? Document will related to the terms, but what's the purpose of this? (2) add_posting method will add term to a documents. void

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

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

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

There's a bit of an API glitch with Query objects at present. This code shows it off: Xapian::Database("/path/to/db"); Xapian::Enquire enquire(db); // make a simple query Xapian::Query myquery(Xapian::Query::OP_NEAR, phrase, phrase + 2); enquire.set_query(myquery); // Now change the query - this shouldn't affect the query enquire // will run, but it does.

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?

Hello, This is a somewhat idle question about Enquire::get_mset(), possibly based on wrong assumptions on how Xapian works, but I would be grateful if someone satisfied my curiosity.

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

Hi, I've just noticed that set_max_wildcard_expansion() has been removed in favour of set_max_expansion() in Xapian. Has the new method been added to the Perl-bindings? We have some old Perl code that uses set_max_wildcard_expansion(), and I have a test of too large expansion that now returns "something terrible happened" instead of"Exception: Wildcard ... expands too much

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_,

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

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

1.Could you explain why are these libraries included in all the xapian-letor headers? #include<xapian/intrusive_ptr.h> #include<xapian/types.h> #include<xapian/visibility.h> Or just provide me with the documentation of these header. I looked into these header files but couldn't anything substantial. 2.
