It's not clear where the problem is.

select to_tsquery('english', '(yellow | blue) & (red | black)');
                 to_tsquery
---------------------------------------------
 ( 'yellow' | 'blue' ) & ( 'red' | 'black' )

select to_tsvector('english', 'yellow red') @@ to_tsquery('english',
'(yellow | blue) & (red | black)');

The only thing I can see that could cause problems is you may have
previously "mangled" words in the ilike query while you'd leave that
task to ts engine that will find a proper lexeme.

Could you be more specific about the problem you're encountering.
