[Xapian-discuss] Working Demo for WWW Search Engine

[Kevin SoftDev]

Olly,

It works except the city is spelled praha, prague is the english version
http://nitra.net/cgi-bin/hladaj.cgi?a=q&q=praha

I fix the content-type becaused I forgot to print the header from Perl
script. One bug is still there that it works only with one term based on the
Perl demo script that came with Xapian. As soon as user type two terms
nothing come up. I am not sure if this is bug of Perl API or is mine.

example with no results:
http://nitra.net/cgi-bin/hladaj.cgi?a=q&q=prahga+hrad


---- one term is called from the Perl script example like this:
    my $enq = $db->enquire( 'Praha' );

--- two terms is called like this?
my $enq = $db->enquire( 'Praha Hrad' );

I do not get any result back, I am wondering if there is another API I
suppose to use .

Thanks, Xapian was very easy to implement and it is the fastest from all
search engine I build, that includes MySQL 5.0,  MS SQL 2005, Lucene and
some other custom commercial.



#!/usr/bin/perl
#-----------------------------------------#
use Search::Xapian;

  my $db = Search::Xapian::Database->new( '/path/to/database' );

  my $enq = $db->enquire( 'Praha' );

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

  my @matches = $enq->matches(0, 20);

  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();
  }
