Usually my directory has over 1k indexed pages and now the number increasing skyrocket, lots of pages like: cbgred.com/index.php?search=games cbgred.com/index.php?search=funny cbgred.com/index.php?search=seller all with www.... Those pages are not alive why Google indexed them?
if it's phpld why dont you just add something to stop the search from being followed? in header.tpl {if $search} <meta name="robots" content="noindex,nofollow"> {else} <meta name="robots" content="index,follow"> {/if} that should eliminate the indexing and following accordingly
