Is there a field the two indices share?
For the sake of argument let's call that field "equipment_id" and assume it is of the type
I'm guessing the field is of the type
text and hidden in the text are some references to items of equipment. If the pattern of an equipment_id is sufficiently unique (e.g. always an 11 digit number) then it might be possible to use a regex to extract these values from the text and place into
keyword type field called
equipment_id which is an array. Let's also assume each document has a keyword field called
Given this setup it would be possible to create a graph of
equipment_id values and how they are connected purely using the document index (ignoring the equipment index).
This is mostly speculation about your data so I think you may need to fill in some more details about the problem here.
