I've indexed some sample data in my elastic node. I can search and retrieve the documents. Now I am trying to see the relationships between these documents using Graph plugin. I've attached a sample document from my index. I want to build the relationship if the entities "\_id" field is in another documents "source-entity-ids" field. i.e. show entity 1 is derived from entity 2 and 3.  
In kibana I can see my index name and the fields in it, along with a query field. But I am not sure how I can create this relationship. I've tried few things but am not getting any results back.

{  
\_index: "sample",  
\_type: "entity",  
\_id: "1",  
\_version: 5,  
found: true,  
\_source: {  
entity\_name: "Some war file",  
category: "AWS\_S3\_object",  
source\_entity\_ids: [2, 3]  
}  
}

Currently, and for reasons of simplicity, we don't provide a way for you to declare that values found in field X can be looked for in field Y. We could conceivably go further and say that field Y is in a different index. Such a mapping will require detailed configuration and so is not in the current release.

For now, you'll need to create a single "ids" field with an array containing both parent and child IDs.  
Because all of these IDs are in the same document in your example you'd end up with a triangle with links 1-\>2, 1-\>3 and 2-\>3. If you want to avoid the 2-\>3 association you would have to create individual docs to express just the 1-\>2 and 1-\>3 pairings - these docs would be more reminiscent of the "edge" objects in a classic graph DB.

The troubleshooting guide has a section on adjusting the link relevance settings in the API. In the GUI, these are controlled by turning "significant\_links" off and setting the certainty threshold to 1.
