I want to use elasticsearch on my backend and I have few questions:
My DB contains semi-structured data of products, i.e. each product may have different attributes inside it.
I want to be able to search a text on most of the fields and also search a text on one specific field.
What is the recommended way to store the document in ES ? to store all text in on field (maybe using _all feature) or leave it in different fields.
My concern of different fields is that I might have a lot of indexes (because I have many different product attributes)
I'm using couchbase as my main DB.
What is the recommended way to move the documents from it to ES, assuming I need to make some modifications on the document ?
To update the index from my code explicitly or use external tool ?
