So in my native language i often used "w" as first letter in sentence since it's have meaning sth like "in" and when i do so it automaticly makes me go search in wikipedia which is so anoying ..... Is there a way to change those keywords or just delete them?
If you use quotes or explicitly list a search keyword, it should be fine. But no, you can't change the built-in searches at all, including changing the keywords.
