Search for products

1.3.5 sp4 question hopefully someone can help

When you do a search in search box and type in what you need to show up like “car parts” for example I want car parts to show up only, but get alot of items not even related to my words just pages of stuff and parts are in the mix but do not even have the word car or parts in most.

I add in search words for each item in admin area but does not seem to help, how do we as a customer just looking for a paticular item and type in box and only those related to it are popping up
