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

Hi, Sorry to follow up on an old thread, but I am wondering if there has been any work done on, or interest in, increasing the maximum document id beyond a 32bit limit?

There's a bit of an API glitch with Query objects at present. This code shows it off: Xapian::Database("/path/to/db"); Xapian::Enquire enquire(db); // make a simple query Xapian::Query myquery(Xapian::Query::OP_NEAR, phrase, phrase + 2); enquire.set_query(myquery); // Now change the query - this shouldn't affect the query enquire // will run, but it does.

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, I have a problem when trying to define a query and setting for each term its "term frequency" with the classical constructor Xapian::Query<http://xapian.org/docs/apidoc/html/classXapian_1_1Query.html#f396e213df0d8bcffa473a75ebf228d6>(const std::string &tname_,

Dear all, I try to use the xapian-compact tool to merge several databases. I need to keep the document ID. The problem is that xapian-compact is not able to merge databases because of overlapping "doc ID range". Nevertheless, in my case, a doc ID is always used for one and only one database. Is there a (other) clever way to simply and quickly merge databases ? Regards 2011/3/7

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

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 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>

Hi, I've just noticed that set_max_wildcard_expansion() has been removed in favour of set_max_expansion() in Xapian. Has the new method been added to the Perl-bindings? We have some old Perl code that uses set_max_wildcard_expansion(), and I have a test of too large expansion that now returns "something terrible happened" instead of"Exception: Wildcard ... expands too much

hi, i am newbie to xapian and am trying to get started with it in python. there is no stemmer.stem_word method in the latest python library. how do i stem words before doing doc.add_posting? is there any sample hello world code in python that i can use? thanks a lot! >>> stemmer = xapian.Stem('english') >>> stemmer. stemmer.__call__

Hi, I need to modify the stemming for a couple of words (a blacklist) and for all the other to use the usual snowball stemmer. The "natural" way of doing it would be to derive from Stem and override operator ()... but I am using *python-bindings*. Would this be possible? If not I have two other solutions in mind: - add a custom stemmer to Xapian - write custom index & search

i use the perl interface of Search::Xapian to index documents, now i got metadata i store with the index like title, date, author, .. and i wonder how to retrieve them from the index again without pulling them from the database. i am pretty sure this is a stupid question and that the answer is obvious i dont seem to be able to find it. regards m
