}
},
"size": 1000,
"_source": {
"includes": [
"modelName",
"vendors.id",
"manufacturers.id",
"id"
]
}
}
So what I am doing here is something like this:
Select * from data where
(manufacturerIds is null and vendorIds in 87) or
(manufacturerIds is null and vendorIds in 56)
But it is returning results like this:
"hits" : [
{
"_index" : "onoff-live",
"_type" : "_doc",
"_id" : "130011",
"_score" : 5.0,
"_source" : {
"modelName" : "Galaxy A20",
"manufacturers" : [
{
"id" : 216
}
],
"id" : 130011,
"vendors" : [
{
"id" : 23
}
]
}
}]
I don't know what I am missing, please give me suggestions, if you want mapping I will post it in reply...
