Since there were no responces for a while, I went with another solution.
Splitted search string to words like you but converted query to

select
+case when productname ilike '%red%'  then 2 else 0 end
+case when productdescription ilike '%red%'  then 1 else 0 end
+case when productname ilike '%cat%'  then 1.7 else 0 end
+case when productdescription ilike '%cat%'  then 0.7 else 0 end
from products
order by 1 desc
limit 100

This allows to define relevance.
Is my solution reasonable ?
