Need some help for creating my model

Elastic Stack Elasticsearch
1

Hello, i am new to elasticsearch and i need some help/hints for creatine my
model. For my relational database ( mysql ) is have the following situation:

Table: Subcategories
Columns: Name, Company

Every subcategory has a name and has a 1:n company relation.

The next is:

Table: Company
Columns: Name, Subcategory

Every company has a name and has a 1:n subcategory relation.

How can i modelling this for elasticsearch. I have a serach form with the
following situation: The user can serach for subcategories, but only one
should shown with have a company assigned. Then you select a subcategory
and omitted the subcategory id. Then only companies should shown which are
assigned to the subcategory.

For some hints i would be very thankfull.

Thanks

Stefan

This might help:

Out of the box, you can't model many to many in ES (unless you do it
yourself in code). One to many is supported using either nested or
parent-child.

Hello,

many thanks to your answer.
Could you give me a little example how to add/remove a single child to a
parent object, maybe.
I would like to do this with the elasticsearch php module. Is this possible?

Regards Stefan

So assuming you want parent/child (assuming you already set up the mapping
correctly), to add a child to a parent:

curl -XPOST localhost:9200/test/child/child1?parent=parent1 -d'
{
"state" : "Ohio"
}'

To delete the above child:

curl -XDELETE localhost:9200/test/child/child1
