That's usually not a difficult problem, since you already have a way
to turn criteria from a web form into a search, and you're just adding
one more criterion to the pile.

I'm not an expert on RDBO, but I believe you would need to call a
different class (the posts class, not the users) and adjust the
criteria you pass, e.g. change "last_name => 'Smith'" to
"user.last_name => 'Smith'".
Any set of ORM tools is going to have different unique features, and a
full abstraction would mean giving up all of the unique features.
However, it looked like Peter was trying to do something at a pretty
high level where hopefully the differences don't come into play much.
