similar to: Fwd: FLAG_PARTIAL and subset words

Hi everyone, Sorry if this is an easy one, but I've Googled and can't find anyone else who's mentioned this same problem. I'm using Xapian (tried both versions 1.0.17 and 1.2.4) with the PHP bindings on Ubuntu 10.04 (Lucid) and Apache 2.2.14. I'm using it for an "auto-complete" in the search form on a web page. But whenever I use FLAG_PARTIAL on my search, the

Hi, I'm using xapian to build my search engine, but met with a problem. The code snippet is like: ----------------------Code begin------------------------------------------------------------- Xapian::QueryParser qp; qp.add_prefix("Singer", "S"); Xapian::Query query = qp.parse_query("Singer:s.h.e",

I want to be able to do searches with FLAG_PARTIAL and some without. Most searches without but with the PARTIAL for an autocomplete widget. I'm using xappy and I can't find where to send the flag when I build up the query. The docs talk of setting up the database with or without FLAG_PARTIAL but that's probably not what I want. Peter

Thanks that helped :). I am still trying to cover add_value some more though since I seem to not understand it totally. I guess it is because I am used to Lucene and Sphinx and Solr and it appears that Xapian seems to attach the type of value stored more on add_value. Like for example I am still a bit confused on how slotno actually works and what it actually is. I think the main thing is

Hello everyone, I'm trying to do an "Auto-complete" widget for the search field on a website, which has Xapian running behind it. (Using the PHP bindings.) I have the name of a search result prefixed with "name", so as the user types, it triggers a search for "name:whatever the user put in". This seems like an ideal use for the FLAG_PARTIAL flag; in fact the

In current Xapian SVN HEAD, there is a bug in the query parser concerned with the handling of wildcard terms with a "+" prefix. Specifically, a query such as "+foo* bar" will be parsed by the query parser into Xapian::Query("bar") if there are no terms in the database which start "foo". Instead, since the "+" term cannot be matched, I believe

Hello. There are several problems I couldn't find a solution. 1. QueryParser does not perform stemming I am working with PHP5 and use the xapian wrapper written by Daniel M?nard I build a query using parseQuery. Output of the parsed query shows that terms are not stemmed, although a stemmer is set ( see code snippet) # create a XapianDatabase object to search in $db = new

Please keep replies on the mailing list — more people can help (and benefit) that way :) So OP_NEAR looks for its terms close to each other (hence "near"). The window is how far away they can be. Probably the easiest way to play with this is using the NEAR syntax in the query parser. So if you had a plain text document: I am walking, always walking. And index it in a very simple

Hi, I'm currently using PostingSource to add some weight over the result using a value. I didn't find any documentation on how to use it with the query so i link a query constructed using the posting source and a query made using the query parser with an AND operator : Xapian.Query queryText = parser.ParseQuery("test:" + textBox1.Text + " DS:1 DS:2"); Xapian.Query

Hello, include <iostream>#include <string>#include <xapian.h>struct document{ std::string title; std::string content; std::string url;}; void indexData(document d) { try { Xapian::WritableDatabase db("/Users/ramesh/Desktop/xapian", Xapian::DB_CREATE_OR_OPEN); Xapian::TermGenerator indexer; Xapian::Stem

This is probably more useful to the general list. Thanks for the update, Dave — was this based on the previous golang bindings?

Hello, Do xapian has analyzer like EdgeNGram to use it for autocomplete. I am trying to use the auto completion using xapian. For example: e ex exa exam example etc.. so that we can get it. I tried to use using the Partial flag but it dose not work Xapian::Query query = parser.parse_query("m*",parser.FLAG_PARTIAL); Do you have any example or any tutorial is appreciated. --Naveen.

Hi all, I''m working on the EventLog#read method for the pure Ruby version of win32-eventlog, but I''m stuck on the get_description private method. Here are the problems: * I don''t think I''m advancing the EVENTLOGRECORD properly between iterations. Take a look at the end of the "while dwread > 0" loop. I get some records, but not all of them.

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

Hi, I am currently trying to benchmark a multithreaded xapian implementation on a chameleon baremetal instance written in C++. My workload is a 3 Gig wikipedia xml dump consisting of ~286 file of different sizes. My results are showing me that indexing on xapian is an order of magnitude faster than my lucene and lucene plusplus implementations. This is a result that I did not expect. Just want to

Hi everyone, I tried sending a message as a reply a while back on my previous topic, but it didn't go through. (Tried Gmane), not even when I 'authorized' the reply. So I'll just paste it here for reference, below this message. It might help some people. But now I have one other small problem, and I'm not sure if it is actually my mistake (although I'm pretty sure it is
