#!/usr/local/bin/perl
# looply.pl
# A typical Google Web API Perl script
# Usage: perl looply.pl <query>

# Your Google API developer's key
my $google_key='insert key here';

# Location of the GoogleSearch WSDL file
my $google_wdsl = "./GoogleSearch.wsdl";

# Number of times to loop, retrieving 10 results at a time
               my $loops = 3; # 3 loops x 10 results per loop = top 30 results

use strict;

# Use the SOAP::Lite Perl module
use SOAP::Lite;

# Take the query from the command-line
my $query = shift @ARGV or die "Usage: perl looply.pl <query>
";

# Create a new SOAP::Lite instance, feeding it GoogleSearch.wsdl

my $google_search = SOAP::Lite->service("file:$google_wdsl");

# Keep track of result number
               my $number = 0;

               for (my $offset = 0; $offset <= ($loops-1)*10; $offset += 10) {
 # Query Google
 my $results = $google_search -> 
  doGoogleSearch(
    $google_key, $query, $offset, 10, "false", "", "false",
    "", "latin1", "latin1"
  );
 
 # No sense continuing unless there are more results
               last unless @{$results->{resultElements}};
 
 # Loop through the results
 foreach my $result (@{$results->{'resultElements'}}) {
 
  # Print out the main bits of each result
  print
   join "
",  
   ++$number,
   $result->{title} || "no title",
   $result->{URL},
   $result->{snippet} || 'no snippet',
   "
";
 
 }
}

Notice that the script tells Google which set of 10 results it’s after by passing an offset ($offset). The offset is increased by 10 each time ($offset += 10).

Run this script from the command line, passing it your preferred query:

$ perl looply.pl "query"

% perl looply.pl
Usage: perl looply.pl <query>
% perl looply.pl "learning perl"
