Filter inside of array of objects

Elastic Stack Elasticsearch
1

Please help out a ES newbie here.

My data looks like

obj1 : {
foo : [ { name : "almond", amount : 4 }, {name: "cashew", amount : 5}]
}

obj2 : {
foo : [ { name : "almond", amount : 5 }, {name: "cashew", amount : 5}]
}

if I only want to use a filter query to retrieve data that has 5 almonds, how should my filter look like?

I tried

{filter : {"bool" : {"must" : [{"term" : {"foo.name" : "almond"}}, {"range" : {"foo.amount" : { "eq" : 5}}}]}}

and I would NOT want obj1 to be returned, but it will because one of the objects in the array satisfy the first must query, and another one of the objects in the array satisfy the second first query.

Thanks in advance.

Have you tried coding this sober?

Your data should look like this:

{"foo":{"almond":4, "cashew":5}}
{"foo":{"almond":5, "cashew":5}}

Now you can access "foo.almond" as the amount and do the query like this:

{
"query": {
"bool": {
"must": [{
"term": {"foo.almond": 5}
}]
}
}
}

Where have you seen the "eq" parameter for the range query, I could not find
it and it even don't work.

Here's the range docu:
