Hi all, public-inbox allows searching for git blob names (e.g. "badc0ffee") in patches. Initially, I chose to use add_prefix for probabilistic terms, since I assumed it could be a superset of what boolean searching offered. Unfortunately, it doesn't seem to be the case because stemming is interfering. So switching to boolean filtering seems to work; and it is fine for mechanical

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",

Hi guys I'm trying to figure out how I can use probabilistic searching on a given field within a document; I've written to the list about this before, but haven't quite figured out what's required and, following a little research, I think I understand what I need to do but I'd like a clarification on this. o We have a database of a number of documents, with fields: title,

Hello, I want to let user specify by drop down list to what fields his query will be searched. For example "Full-text" or "Title+Author", then user enters search query as usual (without using prefixes). But how to modify query so it cover two fields in a right way? For a starter how I think about modifying query to limit it just to single globally selected field: 1. after

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

Hello, I'm wondering about how the QueryParser parses a query containing an "alias" when the default operator is OP_AND (by "alias", I mean a search field mapped to multiple term prefixes). With the following php code : <?php $parser=new XapianQueryParser(); $parser->set_default_op(XapianQuery::OP_AND); $parser->add_prefix('alias', 'AUT1:');

I have an application for synonyms for tags in in notmuch, which means synonym expansion for a particular boolean prefix. I have a vague memory of Olly telling me this doesn't work, but I'm not sure about the details. My higher level goal is to support a kind of indirection with tags, where query tag:foo can really generate tag:bar or tag:fub, depending on some kind of configuration.

Today we noticed that keywords can't be searched as prefixed terms. Or that's what it looks like anyway. I tested and, or, and not. ╰─% NOTMUCH_DEBUG_QUERY=y notmuch search 'subject:"and"' Query string is: subject:"and" notmuch search: A Xapian exception occurred A Xapian exception occurred parsing query: Syntax: <expression> AND <expression> Query

Very few people seem to be using synonym in Xapian, I recently found some problems in the use of synonyms. Normally, I think we should not contain any prefix info in synonym table except that 'Z'. For example, I have the following synonyms and prefix info: db.add_synonym("search", "find"); db.add_synonym("Zsearch", "Zfind");

Hi, I have been looking at xapian for a project and have so far been very impressed. I have hit one major problem the final architecture requires that the web server be a deferent machine from the server that xapian is installed on. With my test code using local database ($db_path = "/var/xapain_db/default"; $db = new_database($db_path);) a query takes around 0.012 seconds on

Hi All I was wondering if anyone had a solution for the following problem. I user QueryParser to stem my documents before adding them to a database. During the stemming process I would like to find a way of keeping proper nouns that span two or more words together as a phrase. For example "New York" or "Gordon Brown" or "Prime Minister" get spilt up. I see

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.

Olly and I have been discussing details of our policy for deprecating features, and we thought it would be useful to canvas users opinions on a particular aspect. From time to time, we remove features from the library (usually because we have a better replacement). To make life easier for users, we've been following a deprecation policy, so that users are given plenty of warning of

Hi, I do not understand the stopword function... I've set the termgenerator like this: $self->{'Stemmer'} = new Search::Xapian::Stem(german2); $self->{'Stopper'} = new Search::Xapian::SimpleStopper(); $self->{'TermGenerator'} = new Search::Xapian::TermGenerator; $self->{'TermGenerator'}->set_stemmer( $self->{'Stemmer'} );

Dear Xapian users, I try to index some German text with Xapian using the xapian_php bindings.
