@short search routines to find items which match given parameter
@descr Mostly we search for a type first and get all information about filter, detector and loader
services from the other configuration tables which are registered for this type.

the first entry. If these return a value different from <empty> you can work with these value.
If found value isn't the right one - you can call search method again.
DONT'T CHANGE THE VALUE OF "rStartEntry" between two search calls!
You can use returned value as parameter for getBy...Name() functions of this implementation too!
