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

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?

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. Xapian::MSet Xapian::Enquire::get_mset(Xapian::doccount first, Xapian::doccount maxitems, const Xapian::RSet * omrset = 0, const Xapian::MatchDecider * mdecider = 0) const I had assumed that the "first" parameter referred to an index in the result set as filtere...

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

...hile the match is running, get_mset(2000, 1000) needs to track 3000 entries so this won't reduce your heap usage (at least not peak usage). Is the heap usage problematic? Looking at the code, for git master each entry is currently: double weight; Xapian::docid did; Xapian::doccount collapse_count; std::string collapse_key; std::string sort_key; We're always going to need the docid, but the other fields aren't always needed and this could be slimmed down depending on what options are in use if the size is causing problems. It is as it is just for si...

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

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
