Patching Google Search engine/application in Unix.

Hi Unix Gurus,

In my Co. we have intranet site hosted on Unix box. In Explorer there is a text box for searching information on internet. By default it is using Google Custom Search. This search engine is little old one. Now I want to patch this search engine with latest patch. If any one know the procedure please let me know in details. As I am now to this kind of activity.

Can we combine two patches into a single and execute in a batch process?

Please let me know ASAP. It is urgent please

Thank you in advance.
