similar to: xapian query group result by domain?

Hello It is possible somehow to give higher priority to recent document. For example, when adding new document to the database, I will add a term that specifies date of the document. During the search, the date of the document is taken into account in the algorithm that calculates document relevancy. In another project I am working on, I would like to limit number of pages returned from the

Hi all, I am trying to implement an Incremental indexing scheme. The problem is that usually the modified documents are large but the modifications are limited. Ideally, I would like to reindex only the modified parts of these documents. If I am not mistaken, xapian cannot do that. Are there any other approaches? It would be nice if xapian supported something like the SQL "group by".

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

Greets, Is it possible to obtain the actual match count if you're using set_collapse_key()? ie, the total count *before* the collapsing occurs (without using get_mset()). Alternatively, will MSet::get_matches_estimated() return the true - pre-collapse - count, or will it also be affected by collapsing? Thanks Henry

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

I'm seeing 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 (

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

"Another use is to group matches in a particular category (e.g. you might collapse a mailing list search on the Subject: so that there's only one result per discussion thread). In this case you can use get_collapse_count() to give the user some idea how many other results there are. And if you index the Subject: as a boolean term as well as putting it in a value, you can offer a link to a

Hello all. I have a problem with collapsing by a key in a compound database. I have 2 databases (e.g. clients and client branches), both of them have the same attribute (with the same valueno), `client_id'. What I need is to search in both these databases and collapse results by `client_id' to get client IDs (set_collapse_key is used with collapse_max=1). The problem is that I receive 2

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

My code is not on Github. I am using the tarball as of now.

I'm trying to compact (or at least merge) multiple databases, while stripping search records which are no longer required. Backstory: I've inherited the Cyrus IMAPd xapian-based search code from Greg Banks when he left Opera. One of the unfinished parts was removing expunged emails from the search database. We moved from having a single search database to supporting multiple

Friends, I would like to hear from anyone who has experience deploying Xapian on Android. I'm new to Xapian, but I know it is used by a couple partners for offline projects on Linux and Windows. Our small nonprofit, WiderNet, provides off-line access to thousands of Web sites for people who lack Internet connectivity (www.widernet.org). Over 2,000 universities, schools, health care sites,

I''m new to ROR, and am working my way through the Agile Web Development Book. In the test application, the authors tell me to test my database connection by performing "rake db:migrate".
