Writing DSL Query to find documents for dyanmic fields in the index

Open Source Elasticsearch and Kibana
1

Hi All,
I want to write a DSL Query that will fetch results from fields.

GET condition/_search
{
    "query": {
        "range" : {
            "tag.value" : {
                "gte" : "operational.threshold",
                 "lte" : "threshold.caution",
                "boost" : 2.0
            }
        }
    }
}

As I write the above code, it’s throwing an error of number format exception.
Is there any way to find integer values using fields instead of integers in the code? As the field threshold.operational and threshold.caution dynamic fields means integer values will change with respect to time so I cannot use static integer values.
Values I am comparing in code are as below-

tag.value
5.7
	
threshold.caution
5.5
	
threshold.operational
0.5
	
threshold.warning
11.2
