Hi, in my opinion searching within kdehelpcenter is pointlessly irritating:
- each time one has to check Unix Manuals and application manuals (or to change the scope selection to all)
- each time one has to change the hits number from 5 to 1000
that's 2/3 clicks at each search...

The handbook does not mention any way to change the default scope selection from none to all.

I advice you to change the two settings above, letting people see the maximal amount of information by default:
that is a more reasonable choice in an help viewer than just showing nothing without a scope selection or showing
the first 5 hits in alphabetical order after that a scope has been selected.
(EG if one searches ls that hit is below the 50th in the list ...)

Thanks for your time
