The following error: "The sort operation used more than the maximum 33554432 bytes of RAM." I have a find() that returns more than 9,000 records and I need to sort them by a nested field with 4 levels: array -> id -> id -> string 'items.xxx_id.xxx_id.name' I know it is possible to increase the total memory that can be used, but is there another way? Or testing whether the index is actually working. I tried increasing the memory to 64 MB and that didn't work either.
