Elastic Search Fliter on two fields within same sub document - elasticsearch

Question

I am trying to write an elastic search query where I have an array of sub-documents with exactly same structure and I have to check two conditions within the same sub document.
My data looks like this :
{
"_id": "5672ba7c0d71c93d159c408e",
"productId": "1723913526",
"title": "Digitab Tablet",
"instock": true,
"specifications": [{
"category": "In the box",
"name": "Test1",
"value": "No"
}, {
"category": "Warranty",
"name": "Test2",
"value": "Yes"
}, {
"category": "General",
"name": "Test3",
"value": "Abcd"
}],
}
}
What I am trying is : I should get products where specifications.name is "Test1" and specifications.value of the same sub document is "Yes"
Here is the Query that I have written for the this:
{
"query": {
"bool": {
"must": [
{
"wildcard": {
"specifications.name": "Test1*"
}
},
{
"term": {
"instock": "true"
}
},
{
"term": {
"specifications.value": "yes"
}
}
],
"must_not": [],
"should": []
}
}
}
The issue is - It should not return the product with id 1723913526 because "value": "Yes" is true for "name": "Test2" and not for "name": "Test1".
I hope the question is clear, please comment if more information is needed.
Thanks in advance.

You need to modify your mapping to indicate that specifications is a nested type.
Mapping like:
"mappings": {
"product": {
"properties": {
...
"specifications": {
"type": "nested"
}
}
}
}
And then querying like:
"bool": {
"must": [{
"nested": {
"path": "specifications",
"query": {
"bool": {
"must": [
{ "wildcard": { "specifications.first": "Test1*" }},
{ "term": { "specifications.value": "yes" }}
]
}
}
},
{
"term": { "instock": "true" }
}
}]
}
