Search result details - Display „X von X Standorten haben geantwortet.“

[mzerlik]

After clicking “Details” button, the popup shows how many sites have responded (if it’s possible).
(If the site has not responded, a line is displayed (instead of “0”).)

For example:

[juliangruendner]

@juliangruendner - check if this is possible and if how exactly

[juliangruendner]

@michael-82 , @alexanderkiel , @EmteZogaf
as we do not know the number of expected sites - do you think it would be a good idea to simply make the number of expected sites configurable in the backend?

[michael-82]

If this requires manual updating anyways...why not do this in the gui? I don't see the benefit of looping a config value through from backend to gui.
Can we get the amount of sites a query was dispatched to from the middleware(s)?
