How can i run this query just for find first item in a path with 4 items

Elastic Stack Elasticsearch

hi , the problem is i want to return range of value of a path that are the same with 4 other items , here is the query:

GET composition_value/composition/_search
{
  "query": {
    "nested": {
      "path": "value",
      "query": {
        "bool": {
          "must": [
            {"match": {"value.composition.content.data.events.data.items.name.value": "systolic"}},
            {"range": {"value.composition.content.data.events.data.items.value.magnitude": {"gte": 10,"lte": 40}}}
          ]
        }
      }
    }
  }
}

And the document that i search in it ,is like this :

	               "items": [{
			    		"name": {
 								"value": "Systolic"
>         							},
>         							"value": {
>         								"magnitude": "70",
>         								"units": "cm[Hg]",
>         								"_xsi:type": "DV_QUANTITY"
>         							},
>         							"_archetype_node_id": "at0004",
>         							"_xsi:type": "ELEMENT"
>         						},
						{
							"name": {
								"value": "Diastolic"
							},
							"value": {
								"magnitude": "80",
								"units": "cm[Hg]",
								"_xsi:type": "DV_QUANTITY"
							},
							"_archetype_node_id": "at0005",
							"_xsi:type": "ELEMENT"
						},
						{
							"name": {
								"value": "Mean Arterial Pressure"
							},
							"value": {
								"magnitude": "615",
								"units": "mm[Hg]",
								"_xsi:type": "DV_QUANTITY"
							},
							"_archetype_node_id": "at1006",
							"_xsi:type": "ELEMENT"
						},
						{
							"name": {
								"value": "Pulse Pressure"
							},
							"value": {
								"magnitude": "324",
								"units": "mm[Hg]",
								"_xsi:type": "DV_QUANTITY"
							},
							"_archetype_node_id": "at1007",
							"_xsi:type": "ELEMENT"
						},
						{
							"name": {
								"value": "Comment"
							},
							"value": {
								"value"sasd3213",
								"_xsi:type": "DV_TEXT"
							},
							"_archetype_node_id": "at0033",
							"_xsi:type": "ELEMENT"
						}],
						"_archetype_node_id": "at0003",
						"_xsi:type": "ITEM_TREE"
					}

And i want to check range of "value.magnitude" of "systolic" not items "diastolic , 2 other items"

i want to filter the first item with "_archetype_node_id" attribute that point to "at0004"

Can you rephrase your question, simplify your example, include the schema and show the output that you would like to get? I re-read your question several times, but I am not really sure what you are trying to achieve. Thanks!

yes of course , the question is how can i query on nested type in elasticsearch ,

this is my document that i save in one nested value in elasticsearch :

and this is the result that i want :

check the range of this path only :

composition.content.data.events.data.items.name.value=="systolic"
the value of "systolic" is "beside" not "in above path" and the path of systolic is :

composition.content.data.events.data.items.value.magnitude

but the main problem is here : the path "composition.content.data.events.data.items.value.magnitude" is repeated 4 times , one for systolic of for diastolic and 2 others , but i want get just the systolic ,

and another thing is i want to select the result that i want by "_archetype_node_id": "at0004", property but i cant .

I want to filter the range of magnitude of systolic that _archetype_node_id property is at0004

I think I understand your question now, but to answer your question I would need to see the mapping for this index or better yet have a curl recreation of the problem? The query that you provided might work if you have a single nested level inside value. However, if you have multiple nested levels of documents you need to have multiple nested queries for each level as well.

yes i know this work in single nested type but my question is ,can i separate this items from the _archetype_node_id attribute ?

and this is my mapping

PUT my composition 
{
  "mappings": {
    "composition": { 
      "value":       { "enabled": false  }, 
      "properties": { 
        "value":    { "type": "nested"  }
      }
    }
}
}

i have one value filed with nested type

To do this you would need to have another nested field on the value.composition.content.data.events.data.items level.

you mean , there is no way to get items from items with _archetype_node_id property?

11

There is, you just need to have nested nested object in your mapping.

tank you so much .(sepas)
