Make search possible with more options

[nepumuk-fs]

I'd like to be able to limit my search requests to specific days I travel within a timeframe, which isn't so clear to be choosable or can't be chosen right now.

I'd like to be able to choose (e. g.):

2. Klasse, Bahncard: --, ab: --:-- Uhr bis: --:-- Uhr (Abfahrtszeit) am: TT.MM. (Abfahrtstag), ab: --:-- Uhr bis: --:-- Uhr (Ankunftszeit) am: TT.MM. (Ankunftstag), max. 24 h Fahrzeit, max. ∞ Umstiege, max. 1:05 Std. Aufenthalt (pro Bahnhof), max. 1:05 Std. Aufenthalt (gesamt).
Frühester Abfahrtstag: TT.MM., spätester Ankunftstag: TT.MM.; max. Preis: 40 €

Sometimes they could/may be contradictory, so maybe not all six time options should be chosen at the same time. ;-)
I'm sure that limiting the search/finding options leads to a faster response time of the result(ing) page ;-)

Would it be too far in excess of the scope of this project to include which type of train (not) to choose?

PS: Many questions and ideas, maybe too many for one single issue…?
