search for: matchdecid

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 ValueSetMatchDecider wh...

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 #d...

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 withou...

...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 Xapian::MatchDecider * mdecider = 0) const I had assumed that the "first" parameter referred to an index in the result set as filtered by the MatchDecider, but then it seems strange that you can change the latter from call to call. Under what conditions can you change the mdecider used and keep a consist...

...ot;, and "price <= 500" and "comment count >= 100", "1000 <= click_number <= 2000". And we have two methods: 1, use xapian.Query for terms and xapian.Query.OP_VALUE_RANGE to filter the value. 2, use xapian.Query for terms to get candidates, then use xapian.MatchDecider to filter the value. Which method get a better performance?

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 scoring method is very complicated and cost many time. We do some analyzer, and actually the boolean attribute filter ( A == true and B == false ..) can filter lots of docs, but we found seems the Mat...

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 ?? I just tried to...

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

Can I use xapian for a search like: 'title' has the phrase "dinner jacket" AND 'color' == BLACK AND 'state' == MA AND 'size' == XL What about faceted search? Thanks

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...

James, That was exactly the issue. libmagic.dll.a was in /lib under cygwin. Adding a -L/lib took care of this. This was also an issue with -lpcre, which adding -L/lib fixed as well. Of course, I'm now running up against something else. from make libtool: link: g++ -fshow-column -Wall -W -Wredundant-decls -Wpointer-arith -Wca st-qual -Wcast-align -Wno-long-long -Wformat-security

This is everything which is specific to the bindings : http://svn.xapian.org/trunk/xapian-bindings/php/docs/bindings.html?view=co and some which are not...

Hi all, I'm once again looking for search with date ranges. e.g. All entries before a certain date. I understand that Omega does this by adding keywords for each year, month and day number separately and construcing a big OR query year = 1980 or year = 1981 or year = 1982 .... or (year = 1983 and (month =1 or month = 2 ...)) I think Olly said he was considering adding something to Xapian,

Hi, Currently Omega/scriptindex supports filtering by date. For example, all dates between START and END. Would it be possible to extend this behaviour to include the time? We have documents which expire. In order to filter out 'old' articles, we would like to check if the document date is between START=NOW and END=MAXINT. Best regards, Eric

I just get the latest version of Xapian 1.2.2 and see that the Java bindings still aren't in a package. Do these work? I am trying to hack them into a package but I can't find where the actual swig -java command is being executed from to add the -package command. Any ideas? -- Jarrod Roberson www.vertigrated.com/blog
