simple query question

Thanks in advance:

I want to do a particular type of pattern matching in a string, but am not a
regexp guru. Can ya help?

I want to find a row in a table that has a column that matches a string like

"jack nicholson - one flew over the cuckoo's nest"

but the columns I have are:

actor movie
------ --------
jack nicholson One flew over the cuckoo's nest

What I have been trying is

UPDATE blah WHERE actor LIKE
"jack nicholson - one flew over the cuckoo's nest"
OR movie LIKE
"jack nicholson - one flew over the cuckoo's nest"

of course that doesn't work. So the column in the table is a substring of
the search string. Parsing up the search string seems like the hard way to
do it, is there an easy way to see if a column's value is a subset of the
query string?

<sql idiot mode>
Also, if there is a DB-independent way to do this without a specific
PostgreSQL operator, that would be ideal.

Many thanks,
Dan
