Bug reference: 17468

PostgreSQL version: 13.1
Operating system: Debian 10
Description:
Test 3
SELECT ts_rank_cd(to_tsvector('This function calculates the coverage
density'), to_tsquery('function | calculates'), 4|1); -- 0.062 (X)
SELECT ts_rank_cd(to_tsvector('This function calculates the coverage
density'), to_tsquery('function'), 4|1); -- 0.062 (Y)
How it should be:
1) In test 3 rank Y should be smaller, than rank X (as in test 2).
2) How get difference ranks Y < X when using normalization variant 4 ?Why are you writing the number 5 as "4|1" (4 "bitwise or" 1) in Test 3?David J.
