I found your where clauses not very readable, so I'll give a general
recipe:

SELECT
...
FROM ....
WHERE <condition for first-set-of-conditions> AND
(<first-set-of-conditions>)
OR <condition for second-set-of-conditions> AND
(<second-set-of-conditions>)

EG

SELECT
*
FROM mytable
WHERE ? IS NULL AND (x=y)
OR ? IS NOT NULL AND (x=? OR y=?)
