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

...some rather odd behavior with respect to the match percent that is returned when performing a simple query. It appears that the addition of a filter to a simple OR query will not affect the weight of the match, but will increase the percent of the resulting match. According to the documentation for MSetIterator::get_percent ( http://xapian.org/docs/apidoc/html/classXapian_1_1MSetIterator.html#99514c11a9291175d20fafa73a0839fd) a match should only get 100% if it matches all of the weight contributing terms in the query. I've attached a test case that shows the odd behavior that I am seeing. I had a dat...

HI, all, I am a user of Xapian, and now I have a problem in using it. After using boolean terms to get some candidates of documents (still too much), we want sorted them by self-defined function which is used in Xapian::KeyMaker->operator(). But how can I get the serialise score in Xapian::MSetIterator object. c++ code likes this: class SortKeyMaker : public Xapian::KeyMaker { std::string operator()(const Xapian::Document& doc) const { double score = self-defined-function(doc); return Xapian::sortable_serialise(score); // How get this value in Xapian::MSetIterator } -- 发自我的网...

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 stream. While retrying ->get_document seems straightforw...

I've added MSetIterator::get_sort_key() to master in 9f807b83ab61a943a355a9ff6733299eab8e6bb1, and backported to the RELEASE/1.4 branch in 93ea6216fe8141d6223c869c6bccb039414db0fa, so this should be in 1.4.6 when that's released.

...used to generate the doc for the PHP wrapper can probably be re-used to generate specific doc for the other bindings. So a generic solution would be better. An xml version of xapian.i ? Any ideas ? PS : by working on this, I found some errors which can perhaps be corrected in the sources : - MSetIterator::get_document documents an "it" parameter which does not exist - some methods arguments are not documented and don't have a name in doxygen output (search for '$arg' in the html file) - some methods of the wrapper can not be used from PHP (Enquire:register_match_decider for...

Hi I know it might not possible, but just want to try my luck. say, for a web search engine backed by xapian.... Is it possible to group the result by domain just like google's [ More results from www.abc.com ], when there are more than 1 results from the same domain? Or, anyone have some work around to do it? Cheers Andrey Kong

Hello, guys. Q1. now I have load all the docid and its document data into a dictionary for faster loading data instead of calling Xapian::MSetIterator i; i.get_document().get_data(); but I was happened to discover that the dictionaries got by such two method were different: both methods use DB1, DB2 method 1: Xapian::Database db = Xapian::Database(the path of DB1); Xapian::Database db2 = Xapian::Database(the path of DB2); db.add_database(db2...
