Hi, I'm trying to compile ocfs2 1.2.6 on a 2.6.21 kernel (with rsbac and pax patches), but I can't get this to work .. In 2.6.20 there was an change in the definition of the INIT_WORK macro (http://lkml.org/lkml/2006/12/5/269) this seems to cause my problems (see below) but even after removing the third parameter of the INIT_WORK calls the compile fails (see second compile failure). Can

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

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)

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

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

I am suffering for slow searching performance on Xapian. I am using Xapian for indexing about 150,000,000 documents. It was implemented in C++; The performance of searching was not that fast. e.g. Searching a query, which includes about 20 terms, needs 2 secs avg. For searching, I followed such steps: 1. construct a QueryParser for certain string 2. parse the query to get a Xapian::Query

Dear All, I've tried to build xapian-core 1.4.3 on MSYS2. It fails with attached error (undefined reference to `exp10'). I think it might be missing an explicit link to 'm'. I'm not able to fix this myself as I do not know autotools sufficiently well, but I hope you might be able to help. Cheers, Mario Emmenlauer -- BioDataAnalysis GmbH, Mario Emmenlauer Tel.

Hi, we are an email hosting provider and we are looking at xapian to improve our user experience about email search.
