Applying criteria at the start of a series of views

I have a series of views that provide a final result set e.g view 5 is selec
t
... from view4; View 4 is select ... from view3 etc.
That all works fine, but what this does is include all of the data from
whatever tables are involved even though I need a subset. My typical
scenario is that the majority of the data are in the table(s) involved in th
e
initial view(s)
What I would like to do is pass the necessary parameters to the view(s)
involved so as to limit the amount of data that gets passed along. I'm stil
l
learning the right way to do things in SQL, so I appreciate any insights tha
t
anyone can provide.
TIA,

SQL Server will pass where-clause predicates down through views to the base
tables if it can. If the column in a view is the result of an expression,
however, this won't work.
