I am very new to Odoo and we would like to import products via REST. I cannot find anything about that but is there no native REST Endpoint that I could use to POST my products in bulk? A CSV upload would be rather cumbersome since we have a lot (!) of products (around 1 Million products) and they update from time to time. 

Also is there a straight forward way I can set the product search strategy in the UI, e.g. putting an index on certain IDs we know are frequently searched for? Thanks for any help!
