similar to: Bug in TermIterator::skip_to() ?

Hello, I'd like to be able to retrieve the indexes stored copy of the document text and tried the following: terms = self.db.allterms() terms.skip_to('Q' + uri.encode('utf-8')) term = terms.next() doc = self.db.get_document(term[1]) print doc.get_data() I just wildly guessed that [1] was the docid, but of course it isn't. So the question is, how do I

Hello, 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

Hi, While porting the unit tests from perl for the node binding I noticed a test failed. I basically create a 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

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

I have download source ?1.10? from the internet and build it into lib Then I create a project as the helpdoc said I using vc2005(vc8) The source in my test project is as follow??copy from the helpdoc? #include <xapian.h> #include <iostream> using namespace std; int main(int argc, char **argv) { // Simplest possible options parsing: we just require three or more

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

Is there any way to count the frequency of specific term in one document? I can''t find any method... Do you? -- Posted via http://www.ruby-forum.com/.

Hi, there. I need some help. Is there a way to count frequencies of terms in a document on Ferret? I know that Ferret has IndexReader#terms_docs_for method which counts all documents. I need to count frequencies of terms in a specific document. Some way?? -- Posted via http://www.ruby-forum.com/.

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

I am writing an indexer that will crawl our web site. Following the recommendation here: https://trac.xapian.org/wiki/FAQ/UniqueIds I'm using the URL as the unique ID for each document. I see how to get a document from the xapian database if I know its URL, but what I need is also to be able to find out the URL from the document. Does this mean I need to store the URL in a value in

Sir, I am a 4th yr undergraduate student pursuing my BTech in CSE at IIIT Hyderbad, India. I am interested in applying for Xapian in Gsoc 2014. I had gone through this year's idea page and interested in applying for 'posting list encoding improvements' project. I am good at C/C++,python; which is one of the requirement. I had done gone through the information Retrieval and

Postlists are split up into chunks, so that skip_to can avoid reading all the postlist. Currently the chunk threshold is 2048, but this is checked before adding an entry, so the postlist chunk can actually grow a little larger. Something like 2060 at most. Unfortunately this isn't a good threshold with the default blocksize (8192 bytes). Internally the B-tree splits up items with a large

Is there a fast way to determine how many documents a term occurs in, besides iterating through every document with TermDocEnum? -- Best regards, Stian Gryt?yr

I am suffering for slow searching performance on Xapian. I am using Xapian for indexing about 150,000,000 documents. It was implemented in C++; The performance of searching was not that fast. e.g. Searching a query, which includes about 20 terms, needs 2 secs avg. For searching, I followed such steps: 1. construct a QueryParser for certain string 2. parse the query to get a Xapian::Query

Hi Everybody, Here is the first version of my match for an ExternalPostList, it should apply cleanly to 0.9.5 and 0.9.6. You can use it by first implementing an ExternalPostingSource, then creating a new Query object passing a reference an instance of your implementation to the constructor, see query.h. The ExternalPostingSource implementation is reference counted, so when its no

Hey, I noticed commit 145503bbe4a5bf702cd13cb2e592111e8d7ca89a (Reimplement Database and WritableDatabase, 2017-10-05) added the phrase: "The terms are returned ascending string order (by byte value)" for termlist_begin. Is that also true for the 1.4 (or even 1.2) series? Also, is allterms_begin also the same w.r.t. ordering? Thanks.
