Use two indexes instead of one for hashed urls

Browse Source 
When using `OR` in a where clause, a composite index can't be used. We should use a `UNION` to take advantages of it.
Instead, create 2 indexes on each hashed urls and make 2 queries to find an url. It'll be faster than the previous solution.
