Friendly URL "?" remove ?

I want to remove into link "?"
sample : mywebsite.net/search?search=İphone

I; use seo complette.
I use redicent urls.
journal theme and 2.1.0.2

I have 2 link not friendl
1-search
2-poll result

seo setting dynamic url and friendl url on works.

thank you

No, you shouldn't remove ?, because it's some kind of separator, which separates base URL from query.

mywebsite.net/search - is a base url
search=İphone - query

I'd recommend you to ignore it, because your URL looks absolutely normal and very SE friendly.
