The single-content-search only gives results, if you match excactly the post title.
Example:
Article Title is "Toto: Bassist Mike Parcaro ist tot"
If you type "toto tot", there is no search result.
"toto: tot" instead gives the desired result.
I would say Grid should not consider special chars and also treat words separated with a hypen as separate words ("grid-box" should be found by "grid box")
