similar to: Writing a MatchDecider and exposing it to PHP

Hi guys, I resently used xapian to sort some documents by distance between 2 points. I implemented a MatchDecider which work well. I now tried to implement a Weight scheme to put my document in ascending order depending on the distance... My information to calcul distance is in values in the document. How I can access document values from Weight to be able to add some sum_extra weight ??

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

Hello, This is a somewhat idle question about Enquire::get_mset(), possibly based on wrong assumptions on how Xapian works, but I would be grateful if someone satisfied my curiosity. Xapian::MSet Xapian::Enquire::get_mset(Xapian::doccount first, Xapian::doccount maxitems, const Xapian::RSet * omrset = 0, const

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

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

Dear, guys: I am a beginner of Xapian, when reading the documents, I encountered follow questions. (1) I see the Xapian::Document has a method void add_value (Xapian::valueno valueno, const std::string &value) What's the purpose of this method? Document will related to the terms, but what's the purpose of this? (2) add_posting method will add term to a documents. void

Hi all, I am a new user to Xapian, and now we met such problem. In our case, a document has many attributes which is boolean value, for example( A, B, C ) , and our search query will use certain filter logic ( A == true and B == false ..) to combine with other search logic. We use MatchDecider to implement the filter logic, and now we met some performance problem, because our self-defined

Xapian::valueno is an unsigned type, so you effectively can't pass a negative value in (if you do it'll be converted to a large positive value and would work if used

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 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

The "share" vs "lib" distinction is that "share" is for files which are architecture independent. So executable machine code will (well, should) never be there, only data files, scripts,

HI, all, I am a user of Xapian, and now I have a problem in using it.

But how can I get the serialise score in Xapian::MSetIterator object. c++ code likes this: class SortKeyMaker : public Xapian::KeyMaker { std::string
