Search is a common feature for apps. The basic implementation of search as an information retrieval exercise does not allow for personalisation. A smart priligy where to buy search, that boosts the information retrieval with sorting based on the relevance to an individual, adds to the user experience. This talk will focus on the lessons from a recent implementation of a smart search in an instant grocery delivery app. The discussion will be split in to two parts. Part one will be on the theory of the Support Vector Machine algorithm which is driving the smart search. In part two, I will discuss the agile practices that are needed to put smart search in to production.
