Hi, I store around 300 bits the row in my table. Every bit is a boolean values on its own. I want to do a similarity search by comparing each bit and get every row which has a certain number of equal bits. What kind of index could be useful for scenario? Could it make sense to calculate a kind of hashvalue for each row to filter the rows dirty at first.
