Hi,

Is there a way to use tsearch so that it returns documents that have less
than all the required keywords? The idea is that if a document only has 3
out of 4 terms, it is still returned, but with a lower ranking.

So far I haven't found a way to do this in the documentation. Is there
something like a "maybe" operator? (ie: 'foo&bar&~doh', meaning documents
with foo and bar, and optionaly doh, but those with would be ranked
higher)

Cheers,
Bas.
