I hope the LabelIndexOption has changed as suggested in the above link.

# LabelIndex option

## When creating a label index, create a direction item in the optionos field.

1. 'labelIndex' works for both directions.

2. If there is no specific option, all of them expect to be true. 
  - store indexEdge, store degree

3. If you want to apply a specific option for a specific direction, specify the direction in 'option'.

## Definition

Ex)
  - in direction: drop indexEdge, drop degree  
  - out direction: store indexEdge, store degree 

```
{
    "out": {
        "method": "drop",
        "storeDegree": false
    }
}
```
