NAME

Search::Xapian - Perl XS frontend to the Xapian C++ search library.

SYNOPSIS

use Search::Xapian;

my $db = Search::Xapian::Database->new( '[DATABASE DIR]' );
my $enq = $db->enquire( '[QUERY TERM]' );

printf "Running query '%s'\n", $enq->get_query()->get_description();

my @matches = $enq->matches(0, 10);

print scalar(@matches) . " results found\n";

foreach my $match ( @matches ) {
  my $doc = $match->get_document();
  printf "ID %d %d%% [ %s ]\n", $match->get_docid(), $match->get_percent(), $doc->get_data();
}

DESCRIPTION

This module wraps most methods of most Xapian classes. The missing classes and methods should be added in the future. It also provides a simplified, more 'perlish' interface - as demonstrated above.

The Xapian library is evolving very quickly at the time of writing, hence any documentation placed here would be likely to become out of date quite rapidly, and I do not have the patience to write some which could rapidly become redundant.

Apologies to those of you considering using this module. For the time being, I would suggest garnering what you can from the tests and examples provided, or reading through the Xapian documentation on http://www.xapian.org/, notably the API documentation at http://www.xapian.org/docs/apidoc/html/annotated.html

If you encounter problems, email either me or preferably the Xapian-discuss mailing list (which I am on - subscription details can be found on the Xapian web site).

EXPORT

None by default.

TODO

Error Handling

Error handling for all methods liable to generate them.

Documentation

Brief descriptions of classes, possibly just adapted from Xapian docs.

Unwrapped classes

The following Xapian classes are not yet wrapped: Error (and subclasses), ErrorHandler, ExpandDecider (and subclasses), MatchDecider, Weight (and subclasses).

Unwrapped methods

The following methods are not yet wrapped: Enquire::get_eset(...) with more than two arguments, Enquire::get_mset(...) with more than two arguments, Enquire::register_match_decoder(...) with one argument, Enquire::set_weighting_scheme(const Weight &weight); Query::Query(tname, ...); with more than one argument; QueryParser::set_stemming_options() with third (Stopper) argument;
