Suppose that a user wishes to request information on four of six given terms t₁, 12, 13, 14, 15, and to. How many quadruples of term does this involve? In other words, determine (a) the length of the fully explicit query and (b) show this query: (t1 AND t2 AND 13 AND 14) OR (1 AND 13 AND ts AND to) OR... Tip: if a user wishes to request information on two of three given[terms t₁, t2, and 13, the answer will be a) 3; b) (t₁ AND t₂) OR (t2 AND 13) OR (t₁ AND t3).
