I must correct myself:
There is an automatic that automatically checks the option "Search archives (all except for UC2)" - (had such a case this evening).
My statement above "This is done in almost all cases" came about because since this option was probably
switched on manually at some point beforehand and the subsequent tests were successful.
Unfortunately, it is currently the case that this automatic is very rarely executed.
So far, despite many tests, I have not been able to find out why this option is not always activated automatically.
