Range query on Nested Documents for Keyword Type - 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
Here whats the catch the value field is keyword, not an integer. I know that only for the Integer Range query will get executed. Is there any possible way to find the documents that have a duration greater than 60 ( Painless Query or Script Query ). Like converting the value Field into Integer and then searching the document.
{
"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"
}
]
}

Answer 1

I have added script to get interactionInfo.value>"somevalue". Scripts are slow and it is better to resolve this at index time and use a range query.
Index:
{
"index15" : {
"mappings" : {
"properties" : {
"interactionInfo" : {
"type" : "nested",
"properties" : {
"title" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"value" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
}
}
},
"key" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
}
}
}
}
}
Query:
{
"query": {
"nested": {
"path": "interactionInfo",
"query": {
"bool": {
"must": [
{
"term": {
"interactionInfo.title.keyword": {
"value": "duration"
}
}
},
{
"script": {
"script": {
"source":"def val=Integer.parseInt(doc['interactionInfo.value.keyword'].value); if(val>params.value) return true; else return false;",
"params": {
"value":10
}
}
}
}
]
}
},
"inner_hits": {}
}
}
}
