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

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);

Currently ExpandDecider::operator() and MatchDecider::operator() return `int' for no very good reason that I can see. It would be more natural to return `bool', since these classes are making a "yes/no" decision about whether to include a term in an ESet or a document in an MSet. The problem is that this can't be done without breaking existing user code which defines

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

I would like to write a MatchDecider in C++ and expose it to PHP. I'm able to compile a simple extension and use SWIG to expose a simple function to PHP, but I can't seem to hit upon the right incantation to expose my MatchDecider class. I have a header file declaring my decider, MyDecider.h #ifndef _INC_MYDECIDER_H #define?_INC_MYDECIDER_H #include <xapian/enquire.h>

I got some performance issue for document.get_data() and enquire.get_mset(). It costs 35 seconds for matches = enquire.get_mset(0,200), and 3 seconds for iterating all doc in matches to get_data. Is't normal? My index contains 30millions documents. I use python binding to operate xapian. Bellow it's my index structure # value: 0:date, 1:site # data: json message which contains: author,

Hi, I try to use XapianMatchDecider to filtering results, but the code : $Decider = new MatchDecider_Search($XapianDatabase->_cPtr); $mset = $XapEnquire->get_mset(0, 3000, null, $Decider); Always return : PHP Fatal error: No matching function for overloaded 'Enquire_get_mset' in xapian.php on line 1082 I saw that SWIG was not supporting Directors for PHP, but now, it seems to

Good afternoon I would like to ask if is possible in new version of Xapian some kind of subclasing MatchDecider in PHP. I am developing application where is very complex permission management. so it cannot be stored in fultext database. MatchDeciders are perfect for this purpose. But I dont know if is possible to use them in PHP even if SWIG now supports directors. Now Iam using

HI, We have an index database of products, about 20 million. We had constructed the title and description of products into posting list, and also stored some values of properties into slot, such as the price, comment count, production date, click number of the products. Now we want select some products which satisties specific condition, such as contain the term of "shirt" and

i have 300 millions records and my search file like this , i want the newest 10 results that match my query , so i use boolean search and "enquire.set_docid_order(enquire.DESCENDING)" , but this method seems a little slow . when i remove "enquire.set_docid_order(enquire.DESCENDING)" it run much faster . how can i fetch the newest 10 results as fast as possible? search.py

Hi all, I found that the figure returned by MSet::get_matches_estimated() varies depending on how results are to be sorted. For instance, in my index, value 4 contains date and time in the format "yyyymmddhhmmss". For the same query, the number of results will be estimated to 20000+ when results are first sorted by date and time with set_sort_by_value_then_relevance(4) and to only 100

Hello all. I need to redefine a docid type (and all dependent types) like this: typedef unsigned long long docid; I think it would be enough to edit "include/xapian/types.h", but it isn't so. 1) I've added : string om_tostring(unsigned long long val) { CONVERT_TO_STRING("%llu") } in common/utils.{h,cc} 2) In include/enquire.h (line 438) I've found the

I finally had a chance to spend some time on Olly's idea about generating documentation for the object-oriented PHP wrapper http://www.oligarchy.co.uk/xapian/patches/xapian9.phps >Another way to approach it might be to postprocess Doxygen's XML output >(which would allow mechanical changes to match PHP syntax). > > I wrote an xslt script to test the idea (It is one of the
