| bitmap_or(bitmap1, bitmap2) | Performs a bitwise OR operation on the two bitmaps. | bitmap_or(build_bitmap([1,4,5]), build_bitmap([6,7]))::String | 1,4,5,6,7 |
| bitmap_and(bitmap1, bitmap2) | Performs a bitwise AND operation on the two bitmaps. | bitmap_and(build_bitmap([1,4,5]), build_bitmap([4,5]))::String | 4,5 |
| bitmap_xor(bitmap1, bitmap2) | Performs a bitwise XOR (exclusive OR) operation on the two bitmaps. | bitmap_xor(build_bitmap([1,4,5]), build_bitmap([5,6,7]))::String | 1,4,6,7 |
| bitmap_not(bitmap1, bitmap2) | Performs a bitwise NOT operation on the bitmap with respect to another bitmap. | bitmap_not(build_bitmap([2,3]), build_bitmap([2,3,5]))::String | (empty) |
| bitmap_intersect(bitmap) | Counts the number of bits set to 1 in the bitmap by performing a logical INTERSECT operation. | bitmap_intersect(to_bitmap('1, 3, 5'))::String | 1, 3, 5 |

| sub_bitmap(bitmap, start, size) | Generates a sub-bitmap of the source bitmap, beginning from the start index, with a specified size. | sub_bitmap(build_bitmap([1, 2, 3, 4, 5]), 1, 3)::String | 2,3,4 |
| bitmap_and_count(bitmap) | Counts the number of bits set to 1 in the bitmap by performing a logical AND operation. | bitmap_and_count(to_bitmap('1, 3, 5')) | 3 |
| bitmap_not_count(bitmap) | Counts the number of bits set to 0 in the bitmap by performing a logical NOT operation. | bitmap_not_count(to_bitmap('1, 3, 5')) | 3 |
| bitmap_or_count(bitmap) | Counts the number of bits set to 1 in the bitmap by performing a logical OR operation. | bitmap_or_count(to_bitmap('1, 3, 5')) | 3 |
| bitmap_xor_count(bitmap) | Counts the number of bits set to 1 in the bitmap by performing a logical XOR (exclusive OR) operation. | bitmap_xor_count(to_bitmap('1, 3, 5')) | 3 |
