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

...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've tried building RPMs for RHEL5 and hit this problem in Search::Xapian: make test fails on test 37: ok 34 - check PositionIterator ok 35 - create TermIterator ok 36 - check TermIterator dubious Test returned status 0 (wstat 11, 0xb) DIED.

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 can't get my head around how to use XapianTermIterator to...

Hi, I have had reports that Recoll has become unbearingly slow in some instances. After inquiry, this happens with Xapian 1.4 only, and the part which does not work any more is the snippets extraction. Recoll builds snippets by partially reconstructing documents out of index contents. For this, after determining a set of document term positions to be displayed (around the hopefully interesting

I'd suggest a quick prototype to see if it's worth the effort. * If you're feeding the reconstructed text into something to dynamically select a snippet, then that could potentially be driven from a lazy merging of the positional data (e.g. a min heap of PositionIterator). If the snippet selector terminates once it's found a decent snippet then this would avoid having to decode all the positional data, but it would have to read it to find the first position of every term, so it doesn't really address the data locality issue. It also would have to...

...ons in the xslt file is probably not an option. Perhaps we can use a hand-coded xml file which would be included in "all.xml" by using a modified version of combine.xslt. It would allow to say things like : - ignore methods xxx which have the signature yyy - add documentation for method PositionIterator::get_termpos from what doxygen generated for "operator *" - add documentation for a new method MSet::get_document_percentage (doc in Doxygen format would follow...) I started to test that approach : the code is between comments in the xslt file (search for 'mappings'), and the...
