Say I have a query like this:
SELECT * FROM my_table WHERE name = \"john doe\" AND phone = \"8183321234\" AND email = \"johndoe@yahoo.com\" AND address = \"330 s
SELECT
*
FROM
my_table
WHERE
CASE WHEN name = "john doe" THEN 1 ELSE 0 END +
CASE WHEN phone = "8183321234" THEN 1 ELSE 0 END +
CASE WHEN email = "johndoe@yahoo.com" THEN 1 ELSE 0 END +
CASE WHEN address = "330 some lane" THEN 1 ELSE 0 END
>= 3;
Side note: this will very likely not be using indexes efficiently. On the other hand, there will very likely be no indexes on these kinds of columns anyway.
