I have a generic code which takes my own ConditionTree class and parse it into an Elasticsearch query. For that, and because I don't know the tree's hierarchy, each condition (leaf on the tree) is parsed into an individual indices query. for example, if I have a person index, and i filter on 2 of it's properties - name and address, so the tree will look like: AND ----person.name, equals, "Dave" ----person.address, contains, "London"

and it will parsed into something like:  
GET persons/\_search  
{  
"query": {  
"bool": {  
"must": [  
{  
"indices": {  
"indices": [  
"persons"  
],  
"query": {  
"term": {  
"name": {  
"value": "Dave"  
}  
}  
},  
"no\_match\_query": "none"  
}  
},  
{  
"indices": {  
"indices": [  
"persons"  
],  
"query": {  
"term": {  
"address": {  
"value": "London"  
}  
}  
},  
"no\_match\_query": "none"  
}  
}  
]  
}  
}  
}

so far so good, the issue start with my parent-child index. I have relations index, which each parent has 2 children. if i'll do the same thing here, if one child match for one condition and the second child in the relation match another, those 2 children will be returned.

of course, if I'm putting those conditions under the same "has\_child" block so it works, but it will cause me ALOT of changes in my code because of the way i'm doing the parsing.

Is there a way in my current way to tell Elasticsearch to perform all those blocks on the SAME child?
