You need to extract the top level object and all nested objects that
contain the object you want to access.  YAML and Marshal formats are
not intended to do queries on them.  These are serialization formats
which let you write out a complete object graph.  The easiest is to
just write out one object which references all the things you want
persisted.

Even if you would write items individually you need to remember the
order in which you have written manually and read the stream from the
beginning until you get to the point of interest - if you happen to
want to read the object you wrote last you need to read the whole
stream.

Kind regards
