I'm using Search::Xapian XS from Debian stable and I'm getting what appears to be an unwrapped C++ exception: terminate called after throwing an instance of 'Xapian::DatabaseModifiedError' Using `eval' from Perl5 doesn't seem effective in catching it. I'm using postlist_begin, postlist_end and ++ to iterate a PositionIterator, and reading XS/*Iterator.xs, I see the XS wrappers are missing: try { } catch { handle_exception(); } in several places. Not sure if that's it or if something else (I know C, but am not remotely fluent in C++). Thanks

Hi all. I want to iterate over all the documents in my database. my $pi = $db->postlist_begin(""); while ("$pi" =~ qr/END/) { my $oldid = $pi->get_docid; $pi++; #... } That used to work with Search::Xapian in perl version 1.2, but now with xapian-bindings-1.4.4 it does not seem to. How are you supposed to tell when you have reached the end...

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

...; while (*sources) { srcdb.add_database(Xapian::Database(*sources++)); } /* create a destination database */ Xapian::WritableDatabase destdb = Xapian::WritableDatabase(dest, Xapian::DB_CREATE); /* copy all matching documents to the new DB */ Xapian::PostingIterator it; for (it = srcdb.postlist_begin(""); it != srcdb.postlist_end(""); it++) { Xapian::docid did = *it; Xapian::Document doc = srcdb.get_document(did); std::string cyrusid = doc.get_value(SLOT_CYRUSID); if (cb(cyrusid.c_str(), rock)) { destdb.add_document(doc); } } /* commit all chang...

Hello again, /thanks to Peter for previous response. I've been digging around trying to find sample usage of XapianTermIterator/XapianPositionIterator in PHP. The idea is to code up a test case in PHP to perform snippet extraction (with a possible view to coding a pecl extension in C). I found a C++ sample, but that wasn't much help. I must be dense this morning though, since I

...tshell, some document numbers seem to point to a data blackhole: the docids are returned when searching for the file/doc unique identifying term, but then get_document() fails. A later replace_document() succeeds, but on the next indexing pass, same issue. // success docid = db.postlist_begin(uniterm) // then failure: xdoc = db.get_document(*docid) In this situation, Recoll will try to update the doc. replace_document() then succeeds, and this repeats on the next indexing pass. This is with Xapian 1.2.16 Here follows a slightly edited version of what the user repo...

Hello, I'm still testing PHP5 bindings and I could'nt find a way to delete all documents from a DB without deleting other informations stored in the DB such as synonyms. Since the process of adding synonyms is time consuming, I would like to use the same DB but restart my test without any document in the DB, is this possibile? I could'nt find a delete_all or a method like that, nor

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
