If i need to get parent in the same entity? For exemple if i have Category1 in my entity Category and Category2 in my entity Category and i need to get Category1 (Parent) and Category2 (child) ? This is my problem

from fazlandelasticabundle.

Sorry, can't understand your problem. Can't you just map the parent from the child entity via its property (specifying the same type in the _parent mapping)?

from fazlandelasticabundle.

For example :

I have entity book, in this entity i have association with category. In my entity category i can get parent with method. In my mapping (config.yml) i have this :

book:
mappings:
name: ~
bookCategory: { type: 'object', properties: { id : {type: 'integer'}, name: {type: 'string', index: 'not_analyzed'}, parent: {type: 'object', properties: {name: {type: 'string', index: 'not_analyzed'}, parent: {type: 'object', properties: {name: {type: 'string', index: 'not_analyzed'}}}}} } }
persistence:
driver: 'orm'
model: 'AppBundle\Entity\Book\Book'
provider:
batch_size: 5000
listener: ~
finder: ~

I get my categories but separately.

category : [key,count]
subCategory: [key, count]
subsubCategory: [key, count]

i need this :

category : [key, count, subCategory [ key, count, subsubCategory [ key, count]]]

Thanks,

My aggregation :

public static $AGGREGATIONS : [
'term' =>
'category' => 'accessoryCategory.parent.parent.name',
'subCategory' => 'accessoryCategory.parent.name',
'subsubCategory' => 'accessoryCategory.name'
]
];

What you need can't be done in elasticsearch with parent-child relationship.
With your mapping, to get
category : [key, count, subCategory [ key, count, subsubCategory [ key, count]]]
you just need nested aggregations

from fazlandelasticabundle.

My mapping is good?
My problem is just my aggregations ?
What is path to get this ? :

'category : [key, count, subCategory [ key, count, subsubCategory [ key, count]]]' ?

In public static $AGGREGATIONS : [
'term' =>
'category' => 'accessoryCategory.parent.parent.name',
'subCategory' => 'accessoryCategory.parent.name',
'subsubCategory' => 'accessoryCategory.name'
]
];

How subCategory know it is in 'category' ?

(Sorry for my bad english)

What is path in nested aggregation?
And whats is function addParam? The documentation does not explain

from fazlandelasticabundle.

Excuse me, but this is not a support forum for elasticsearch.
Please refer to the official documentation on how to model your mapping and how to use aggregations, or post a question on StackOverflow, ES dedicated Google groups or other support forum.
