Parse Apache referer logs and extract search engine query strings
This module provides a simple function to parse and extract search engine query strings. It was designed and tested having Apache referrer logs in mind. It can be used for a wide number of purposes, including tracking down what keywords people use on popular search engines before they land on a site. It makes use of URIsplit to extract the string and URIEscape to un-escape the encoded characters in it. Although a number of existing modules and scripts exist for this purpose, the majority of them are either outdated using obsolete search strings associated with each engine.
