Add detailed filtering (see Moozean)

[ChrisBtt]

One search bar might be too unclear for detailed searching. What can be entered, how can it be entered (e.g. range of dates).
Code from Moozean might be used. Available via Dropdown or Button next to simple search bar.

Like in google's image search, there is a simple search bar at the top and to further reduce the resulting exams, more filtering options appear after entering a simple search.

Perhaps this needs to be explained more in detail, I don't know. Or do you think the entire UI is unclear and useless and would like to switch it completely?

We should probably get feedback from more users on this and then decide if the UI should be changed.
