In file:
oc-content/themes/beta/search.php
you have:
<?php if( osc_count_items() == 0 || Params::getParam('iPage') > 0 || stripos($_SERVER['REQUEST_URI'], 'search') ) { ?>
<meta name="robots" content="noindex, nofollow" />
<meta name="googlebot" content="noindex, nofollow" />
<?php } else { ?>
<meta name="robots" content="index, follow" />
<meta name="googlebot" content="index, follow" />
<?php } ?>
change it to:
<?php if( osc_count_items() == 0 ) { ?>
<meta name="robots" content="noindex, nofollow" />
<meta name="googlebot" content="noindex, nofollow" />
<?php } else { ?>
<meta name="robots" content="index, follow" />
<meta name="googlebot" content="index, follow" />
<?php } ?>
