The split filter acts on a single field. You can use a ruby filter to join the elements of each array into another array so that you have this:

```nohighlight
{
  ...
  "field_to_split": [
    ["A", "E", "W", "Q"],
    ...
  ]
}

```

Then feed `field_to_split` to a split filter, and use another filter or two to split the array back into discrete fields.
