Syntax
BITMAP ORTHOGONAL_BITMAP_INTERSECT_COUNT(bitmap_column, column_to_filter, filter_values)
求bitmap交集大小的函数, 第一个参数是Bitmap列，第二个参数是用来过滤的维度列，第三个参数是变长参数，含义是过滤维度列的不同取值
example
mysql> select orthogonal_bitmap_intersect_count(members, tag_group, 1150000, 1150001, 390006) from tag_map where tag_group in ( 1150000, 1150001, 390006);
