Hiyah,
This is a slightly more flexible way of doing pretty much the same thing.
You can then log the output of search_term($HTTP_REFERER) for later analysis.
I've not split the search terms up into words (I'm thinking of how boolean
searches like 'foo AND NOT bar' would skew the results and how search phrases
like 'foo AND "bar baz"' would be split up).
Unfortunately, the analysing the logs (properly) is going to be more of a job.

<?php
function search_term( $referer )
{
// search engines we know about and what they call their search terms.
// Add your own, I can't be bothered to look at any more.
$engine = array (
"www.altavista.com" => "q",
"www.google.com" => "q",
"search.yahoo.com" => "p",
"search.excite.com" => "search",
"www.lycos.com" => "query",
"www.lycos.co.uk" => "query"
);
// if no referer's been passed, forget it.
if(!isset($referer) || empty($referer) ) return false;
// split the url into logical bits.
$url = parse_url( $referer );
// if we don't recognise the search engine forget it.
if(! $terms = $engine[strtolower( $url['host'] )] ) return false;
// parse the query part of the url and put it in $REFERER_GET_VARS.
parse_str( $url['query'], $REFERER_GET_VARS );
// find the appropriate value and return it together with the search engine as a
hash.
return array(
"engine" => strtolower( $url['host'] ),
"term" => $REFERER_GET_VARS[$terms]
);
}
print_r( search_term( $HTTP_REFERER ) );
?>
