Обсуждение: Efficient intersect operation (Full Text Search)

I have a brief question - I can provide more information if it is not clear.

I would like to perform pairwise intersect operations between several
pairs of sets (where a set is a list or vector of labels), I have many
such pairs of sets and the counts of their elements may vary greatly.

Is there a way to perform to "AND" two tsvectors and get the resulting
intersect as another tsvector?

To refine the above question, is there a way to intersect two
tsvectors? In short I would like to intersect two documents.
