We realise our score function using PostingSource instead of using KeyMaker, we reference your python example and source code of xapian, the simple demo is here. https://github.com/xiangqianzsh/xapian_leaning/blob/master/postingsource/ExternalWeightPostingSource.h But we found that using PostingSource is more slower than KeyMaker. I think the reason maybe: We only use...

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_se...

Thanks for you reply. In our case, we want to get a weight using the user' properties(age, gender, price preference) and products' properties(price, comment count, purchased amount among different gender or range of age). So our weight function is complex, no matter we use KeyMaker or PostingSource, six to eight values in slot will be used. But we find that using doc.get_value(slot) several times separately in each search makes getting result slowly. Now we want to constuct a forward index (using unordered map) which uses docid as key and its value contains the slot valu...

Dear Members of Xapian Project, Sorry for troubling you this time. It can be witnessed that xapian will store Document values with serialization approach when given value types meet float/double. Such an approach is deployed on sort_key related fields as well, where the xapian requires KeyMaker::operator() must return an serialized float/dobule variable. Then heap sort comes and ranks the vector<MSetItem> items (multimatch.cc MultiMatch::get_mset()) by comparing serialized sort_keys (std::string) straightforwardly according to <IEEE-754 doubles>. Subsequently sort_keys will...

Very odd this, I have downloaded the latest xapian-core and bindings. Installed xapian-core no problem in /usr/local/xapian However I am getting very strange errors when running make when trying to install the PHP bindings, it configures fine. Paste bin here: http://pastebin.com/JWViJz4b I am missing something obvious I know... I have built 1.0 on this machine in the past fine... John

Hi everybody, Maybe I'm going to ask a bit weird question: I have an item collection, most of them are writting with latin letters, but some of them have chinese letters. There is a list page and numbers, punctuation and chinese letters go first. I would like to change this order policy in order to show first items that start with latin letters, and then numbers, punctuation and chinese

I'm truly impressed by wine, especially Codeweavers'. Not only was it easy to install, but it works! I can now use Britannica, the OED and the archives of Time magazine on Windows CDs. I'm working on getting Pegasus to find my data folders (any tips?) and Agent works fine. It did everything I wanted it to do except run CorelDraw4 (it can't decipher its fonts) and any astrology
