similar to: get_docid???

At least it isn't working the way it used to. Code: $db = Search::Xapian::Database->new( $dx ); my $qp = Search::Xapian::QueryParser->new(); my $dbSize=$db->get_doccount(); # $qp->set_stemmer(new Search::Xapian::Stem("english")); # $qp->set_stemming_strategy(STEM_SOME); # $qp->set_default_op($defaultop); my $par =

Thanks, the Centos 6 repos don't have that rpm and the http://xapian.org/download page seems to only cover the XS bindings, if I am reading this correctly: But I was able to remove the rpm packages and compile and install the core and swig from source.

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 attempt to translate that

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

Hi All, I've installed Xapian and the php module. I've set up a script for use with scriptindex and dbi2omega for getting data from the db into the index easily, the script file is as follows: =============================== id : field=id title : index title: field=title description : index description : truncate=50 field=content ============================= However, when querying

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

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

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

Lately I was reading many articles about using boolean queries for search engine but I haven't seen any complete working demo. Therefore I put together very simple working demo of search engine using boolean query. Feel free to suggest any performance improvement or error while keeping it as simple as possible for understanding. Thanks, -Kevin Duraj http://myhealthcare.com

Newbie-alert: I'm just getting started on a new project involving a full text search requirement, and my initial investigation points to xapian being the way to go. Two questions: - eventually I'll most likely be indexing towards 50 million documents - is this reasonable to expect or attempt with xapian? - each of my documents come with a set of attributes. These are easily stored

Hi, I have just started using xapian and I may sound like a noob. I want to know how i can access the content of the document retrieved while searching. I have used the code found on this mailing list itself to index my database. #!/usr/bin/perl -w use strict; use Search::Xapian; use File::Find; my $DATABASE_DIR = '/home/rohit/Desktop/SET/DB'; my $db =

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

The Database object itself effectively does (it works in a snapshot of the state of the database when you open it, or last called reopen() which

In other words, is it possible to avoid duplicates if new documents are inserted into the DB by another process in-between ->get_mset calls when reusing Xapian::Enquire objects? I do some expensive processing on each mset window, so I always limit the results to limit heap usage even if I'm planning on going through a big chunk of the DB: $mset = $enq->get_mset(0, 1000);

Sorry if this is the wrong forum to discuss Search::Xapian issues -- this just seems like the best place.. Anyways, I've been testing out using $db->add_database() when searching, and it seems like the docids I'm getting out of it are incorrect, almost as though they're "double" what they should be (numerically)... the docids that exist should be around 950,000 and

Hey Hi jiangwen,hope you are doing fine :) You need some libraries and tools installed on your system before you build Xapian and omega.The complete list can be found in the "Building from svn or git" section of this document.:- http://svn.xapian.org/trunk/xapian-core/HACKING?view=co Make sure you have all the required tools installed and it will work fine. Please let me know if you

Hi all, There's been a odd bug reported to us by Daniel Menard while working on the PHP bindings: "I then tried to run the dotest target...All tests passed, except the one about get_matching_terms (smoketest.php line 94). I added this line before the exit: for ($i=0; $i<strlen($terms); $i++) echo $c=ord($terms[$i]), ' ', ($c>31?$terms[$i]:''), "\n";
