Much depends on whether there is intelligence on where to search.
IIRC in the recent "australian maddie" case physical searching wound down quite quickly as the immediate locations were covered off. Where else to look tends to require specific intelligence
The reality is significant resources were being invested
As to what I would expect, in a wealthy country like Germany, obviously I would expect significant searches, as we routinely see. If I was on holiday in Thailand, then clearly i can expect much less. Portugal somewhere in between. But expecting a UK level response is not realistic.
