locate doesn´t seem to include home directory

[Rosika]

Hi all, 

I just stumbled over some curious behaviour. The "locate" command doesn´t seem to include my home directory.

On my desktop I created a text-file "prov.txt", then ran "sudo updatedb" but
"locate prov.txt" didn´t return any results.  :023:

The "find" command however doesn´t have any difficulties finding it.
Is it possible that the home directory is excluded by "locate"?

Many thanks in advance and many greetings.
