Hello, everybody, I am coming across a problem and really need your help. Some URLs of my site that contained parameters such as search_type and index.php=? are indexed by Google, which is not I want. Therefore I want to remove these URLs from index results through Remove URLs function in Google webmaster tools, because the number of URLs like this characteristic is more than five hundreds, so I want to know what command sentence should I entry to achieve this aim? Thanks in advance.

you can use robots.txt and Remove URL tool from Webmaster panel.or else use canonical link script, this is used to clear up duplicate content issues.
