Search suggest shouldn't offer special pages with limited access to users who don't have such rights. Eg. regular user shouldn't be offered Special:BlockIP Special:RenameUser etc...
This is a core feature -> changing product/component.
Search suggest doesn't provide completions on officewiki if you aren't logged in. Is this (similar to) what you mean?
