can any one help im looking to add a search to my site and was wondering if you could use PHP to do so ? if so how easy is it and what programs would i need to use

thanks

Site search engines aint that simple really! Have you tried looking at google? They offer an add-in which allows people to use their engine to search your site! all you have to suffer is having a small google logo next to the search box.

yes iv tryed that one but it dont find all the informaion on the site.
i mainly wont one to find post codes on my site or town names
