...document, add a few terms, add the document to a database and then call doc->termlist_begin().get_termfreq(). This throws "Can't get term frequency from a document termlist which is not associated with a database." What I think this means is that I can not call get_termfreq from a TermIterator obtained from a document (this is only available for a TermIterator obtained from a Database object). Am I right? I will add code snippets if it is required. Thanks, Marius -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.xapian.org/pipermail/xapian...

...llo, Been using Xapian and the Java bindings for years, all was working great, and I all of a sudden decided to upgrade to the latest 1.2.12 and use the new java-swig bindings instead of the old hand-crafted JNI which I think have been deprecated now. I'm struggling with the new design of the TermIterator. More specifically, I can't tell when I've reached the end of the list of terms for my document. If I keep calling next(), it will eventually crash in the C++ code and cause the JVM to crash as well, fair enough. If I call hasNext(), it always returns false, even though there are more ter...

Hi all, I've been toying with xapian (mostly using the Python bindings) and I think I've hit a bug in the TermIterator::skip_to() method (or maybe in QuartzAllTermsList::skip_to()). I've attached a c++ source file that demonstrates the issue. In short, if you have a WritableDatabase, ask for the all-terms TermIterator with db.allterms_begin(), and then skip_to() a word that is itself a term, the iterator somet...

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

If you only look at the terms and wdfs then you could only get DatabaseModifiedError on the call to create the TermIterator since the list of terms and wdfs is stored in a single entry per document which is fetched when the iterator is created (it is conceivable this might...

...ready retrying the ->get_mset operations; but now I'm wondering where I'd hit DatabaseModifiedErrors while inside a Xapian::MSetIterator loop. I assume ->get_document is a place where it gets thrown; but once a document is retrieved, can iterating through terms in one document (using TermIterator) also throw DB modified? I'm dumping multiple terms per-document to a stream. While retrying ->get_document seems straightforward, retrying midway through a documents terms would require me to introduce extra checks/buffering to avoid duplicate terms on reopen+retry. I'm actually redoi...

...base via PHP bindings $xdb_doc = new XapianWritableDatabase(PROJROOT.'/tmp/xapian/doc'.$postid, Xapian::DB_CREATE_OR_OVERWRITE); $xdb_doc->add_document($xdoc); $xdb_doc->commit(); Also, FYI, the documentation here seems incomplete: http://xapian.org/docs/apidoc/html/classXapian_1_1TermIterator.html I had to inspect the bindings to find the rather useful get_term() method of the TermIterator class! It does mention the use of the * operator to return the current term but I can't see how I'd invoke that in PHP. If the get_term method applies in all environments, it ought to be...

Morning All, I use scriptindex to build my database and the PHP bindings to pull it all out. Is it possible to have more than one index but select what the bindings search on? So at the moment I index property addresses, I would also like to index property descriptions for more advanced searching but only as an optional extra...probably in an extra search box. Also I would like to analyse the

One issue left for me to figure out is that in different languages there are different characters and Xapian takes only english characters. Thefore many word entered by users that contains their own language special characters will not return any result. MySQL offers different collations ... Now when I see how much data Xapian can search perhaps I could expand my index spider different European

I'm having trouble translating from C++ to perl objects. The TermIterator class looks like to get a set of terms in a document you might have C++ code like: Enquire::TermIterator termIt =enquire->get_matching_terms_begin(id); for(;termIt != enquire->get_matching_terms_end(id);termIt++) { string term = *termIt; } Or something similar. However when I attemp...

...some adjustments to the multi-database support, but I think otherwise we'll end up duplicating a lot of that machinery in the Lucene backend anyway. I've not looked at the Lucene file structure with this in mind yet though - do you see any obvious problems with this approach? > Xapian::TermIterator it = db_in.allterms_begin(); > This method traverse all terms in the first segment, then the second > segment, until the last segment. Iteration over all terms should return the terms in sorted order (by byte value) and without duplicates, neither of which is achieved by handling each segmen...

Hey Guys, Just making some enquieres for a project i'm goign to be starting using xapian. When searching over a indexed document will i be able to get a list of hits, how many hits and the location fo the hits. I will have boolean searches like eg ("Mysql" AND ("Linux" OR "Windows")) On each hit i will be wanting teh location of the word found and how many

...================================================================= When displaying search results, i would like to to display a piece of the document that is related to the search string (snippet). I have the following idea: 1) first i have to find the positions of the search terms by using Xapian::TermIterator::positionlist_begin() iterator. 2) second, i have to display terms that have positions that are close to the search term position (several terms from the left, and several terms from the right of the search term) So, i know positions of the terms that i want to display. But how to get the terms i...
