create a new col in the same table called __idx_a_b_c that the hash of the concatenated values in that order is stored, create a normal index for that (CREATE INDEX ...)
if a query matches that set of columns then use that indexed col to fetch the desired results from that table
could also work with .in() query if materialized view exists
