require 'sinatra/contrib
    
def get_result( str )
    str = str.to_s

    if str.end_with?( '1=2' ) || str == '-1839'
        'Could not find any results, bugger off!'
    elsif str.end_with?( '1=1' ) || str == default
        '1 item found: Blah blah blah...'
    else
        'No idea what you want mate...'
    end
