For searches I search in, for example, the fields field2 and field3, but I need to score with the field3 of the first group. For example, sequence 1 has more value than sequence 2, and is more than 3 if it exists. There are not always 2.3 or more sequences. Sometimes there is only one,

Should I create an index with the first\_group, and delete those data from the first index documents? Or is it possible to work with this type of data in a single index?

Maybe my level of English does not allow me to advance in what I want to say.

```
{
	"field1" : "sometext",
	"field2" : "sometext",
	...
	"first_group" : [
		{
			"sequence" : 1, // Integer autoincrement
			"field2" : "sometext",
			"field3" : "sometext",
			"date" : "20170120" // Format YYYYMMDD not mapping. ES put type text 
		},
		{
			"sequence" : 2, // Integer autoincrement
			"field2" : "sometext2",
			"field3" : "sometext2",
			"date" : "20170121" // Format YYYYMMDD not mapping. ES put type text 
		},
		...
		
	],
	"other_group" : [
		{
			// Similar 
		}
	]
	"other_group2" : [
		{
			// Similar 
		}
	]
}
```
