BF.MEXISTS works like BF.EXISTS for several items at once. Each 0 is certain (never added); each 1 means probably added.

Return value

Section titled “Return value”

An array with one element per item:

Element RESP2 RESP3
Item may be present Integer 1 Boolean true
Item not present Integer 0 Boolean false

If the key does not exist, or holds another type, every element is 0.

Examples

Section titled “Examples”
