Filtering or Searching on a Form

[Jason]

I have a primary form which contains a number of subforms.
The primary form is tied to a primary table. The subforms
are tied to seperate tables, which are related to the
primary form (and the primary table) through one-to-one or
one-to-many relationships. These subforms on the main
form were created just for displaying the related data.
To edit this related data in the subforms, the user has to
click a button to open another form. My problem is that I
need to be able to apply a filter or run a search not only
on the data in the primary form which comes from the
primary table (which can be edited in the primary form),
but from the other related data displayed in the
subforms. Is this possible? Thanks.
