There are so many assumptions baked into a bayesian search inside your own home that it's unlikely to help though. Plus it relies on at least one hypothesis containing the correct search space (i.e the object lies within the search space).
I agree it's probably not very helpful in this case, though there are some general lessons you could take from it that would be helpful. Considering the likelihood that it would have already been found or could never be found if it were in a particular location can help you prune your search.
e.g.
> "It's likely it may have ended up on my kitchen counter, but if that were the case I probably wouldn't think it lost. So I should deprioritize looking on counters."
or
> "There's a good chance it's in my attic, but my attic is cluttered and I'd probably fail to find it even if I looked there, so I should deprioritize searching the attic until other possibilities have been exhausted."
