Doing a Range Query over particular Nested Document - elasticsearch

Question

I have a document structure like this. For this below two documents, we have nested documents called interaction info. I just need to get only the documents that have title duration and their value is greater than 60
{
"key": "f07ff9ba-36e4-482a-9c1c-d888e89f926e",
"interactionInfo": [
{
"title": "duration",
"value": "11"
},
{
"title": "timetaken",
"value": "9"
},
{
"title": "talk_time",
"value": "145"
}
]
},
{
"key": "f07ff9ba-36e4-482a-9c1c-d888e89f926e",
"interactionInfo": [
{
"title": "duration",
"value": "120"
},
{
"title": "timetaken",
"value": "9"
},
{
"title": "talk_time",
"value": "60"
}
]
}
]
Is it possible to get only the document that has title: duration and their value is greater than 60.Value Property in the nested Document is text and keyword.

Answer 1

There are few basic mistakes in your solution, in order to utilize the range query(ie find a document which has more than 60 value, you need to store them as an integer in your case).
Also please refer this official guide which has a similar example.
Let me show you a step-by-step example on how to do it.
Index def
{
"mappings" :{
"properties" :{
"interactionInfo" :{
"type" : "nested"
},
"key" : {
"type" : "keyword"
}
}
}
}
Index sample docs
{
"key": "f07ff9ba-36e4-482a-9c1c-d888e89f926e",
"interactionInfo": [
{
"title": "duration",
"value": 120. --> note, not using `""` double quotes which would store them as integer
},
{
"title": "timetaken",
"value": 9
},
{
"title": "talk_time",
"value": 60
}
]
}
{
"key": "f07ff9ba-36e4-482a-9c1c-d888e89f926e",
"interactionInfo": [
{
"title": "duration",
"value": 11
},
{
"title": "timetaken",
"value": 9
},
{
"title": "talk_time",
"value": 145
}
]
}
Search query
{
"query": {
"nested": {
"path": "interactionInfo",
"query": {
"bool": {
"must": [
{
"match": {
"interactionInfo.title": "duration"
}
},
{
"range": {
"interactionInfo.value": {
"gt": 60
}
}
}
]
}
}
}
}
}
And your expected search result
"hits": [
{
"_index": "nestedsoint",
"_type": "_doc",
"_id": "2",
"_score": 2.0296195,
"_source": {
"key": "f07ff9ba-36e4-482a-9c1c-d888e89f926e",
"interactionInfo": [
{
"title": "duration",
"value": 120
},
{
"title": "timetaken",
"value": 9
},
{
"title": "talk_time",
"value": 60
}
]
}
}
]
