which tool eBay use to make research of it's own products?
hello, I'm an italian computer student and I'm going to present my thesis on 4th of Dicember. I have a question for your IT department. ElasticSearch and MongoDB wrote on them site that you are using them softwares to research data of your products. I think that the problem them solutions solves is the same. So this is my question : are you using both of them or one of the two web pages is dated? Thanks for the reading, I hope in a Ebay's IT department answer.
