It wont return items that have 'Robocop' entry only.

[local]:5432 postgres(at)postgres=#
select to_tsvector('robocop') @@ to_tsquery('robocop & (dvd | collection)');
?column?
----------
f
(1 row)

But to_tsquery('robocop | (robocop & (dvd | collection))') will do the trick.

[local]:5432 postgres(at)postgres=#
select to_tsvector('robocop') @@ to_tsquery('robocop | (robocop & (dvd
| collection))');
?column?
----------
t
(1 row)
