Elasticsearch AND Parens - elasticsearch

Question

I'm attempting to do the following with the query dsl but I'll express it as SQL:
(matrices.matrix = 'Matrix1' AND matrices.count = 1) AND (matrices.matrix = 'Matrix2' AND matrices.count >= 0)
So, I need to get docs that have both of these nested docs with these values.
This is the nested document it sits on the _source level
"matrices": [
{
"terms": [],
"count": 0,
"matrix": "none"
},
{
"terms": [
"greater"
],
"count": 1,
"matrix": "Matrix1"
}
]
And here is the mapping for the sub-doc:
"matrices": {
"type": "nested",
"include_in_parent": true,
"properties": {
"count": {
"type": "long"
},
"matrix": {
"type": "string"
},
"terms": {
"type": "string"
}
}
}
So, I need to generate a query that will allow me to get docs that match both (matrix = 'none' && count=0) && (matrix = 'Matrix' && count = 1)
Thanks,

So basically you want to retrieve documents that MUST contain two nested documents with the following criteria:
one nested document with matrices.count=0 AND matrices.matrix=none
another nested document with matrices.count=1 AND matrices.matrix=Matrix
Then with the mapping you have, you can achieve that result using the following query. We use bool/must for two nested queries which in turn match the criteria each of the nested documents that must be retrieved.
curl -XPOST localhost:9200/_search -d '{
"query": {
"filtered": {
"filter": {
"bool": {
"must": [
{
"nested": {
"path": "matrices",
"query": {
"bool": {
"must": [
{
"term": {
"matrices.count": 0
}
},
{
"term": {
"matrices.matrix": "none"
}
}
]
}
}
}
},
{
"nested": {
"path": "matrices",
"query": {
"bool": {
"must": [
{
"term": {
"matrices.count": 1
}
},
{
"term": {
"matrices.matrix": "matrix"
}
}
]
}
}
}
}
]
}
}
}
}
}
