Hi Roman, maybe in the meanwhile you could fix/change the current default search options used for the "Search the Community" search box, which is the reason why the OP is unable to find the referenced post when searching "resourceholder".
Right now in order to find something here—most of the time at least—when using it, you need to select More Options->Where->Kotlin.
Ditch the forum altogether and move to stackoverflow.
Stackoverflow is not a forum and there are enough deputy sheriffs there to remind you! ;-) I'm happy that this forum exits as a complement to Stackoverlfow.
