I switched up my importing of a csv file from doing single inserts to a
bulk insert but I'm not sure why all my document are nested in a doc field
instead of inserted as value. There is no 'doc' field in the dataset so I'm
not sure where that value is coming from.
ie:
"hits": [
{
"\_index": "sample-index",
"\_type": "sample\_agg1\_v3",
"\_id": "75a6c925-d37e-49fd-b1ca-3c5355e2d146",
"\_score": 1,
"\_source": {
"doc": "{' ............. the data
instead of
"hits": [
{
"\_index": "sample-index",
"\_type": "agg1\_sample",
"\_id": "83abd750-54d9-4373-8710-5eff29485c9e",
"\_score": 1,
"\_source": { .... the data
