Log search engine Keywords in access-log

[juanmc]

Hello!,
I've been asked to log in the access-log file, the keywords used in search engines, when people click on the link of a website.
ie: Lets suppose I look for "Led Zeppelin" "Vinyls" and in the search engine shows up website.com/vynyls and click on the link, I want in the access log, the terms "Led Zeppelin" and "Vinyls" to be logged as I log the IP address, user agent, date etc.
Is this possible?

PS: I've already looked in Log Files - Apache HTTP Server Version 2.4 , but I didn't found how to do that.

You might find the data in AWstats in your cPanel of use, it provides this sort of thing.
