Nextdoor is the diverse multi-sided marketplace where on the one side we have neighbors having the most diverse sets of intents. Their interests are explicitly expressed in the search bar and form quite a unique demand vector. People are searching for local neighbors to connect with, trying to find classifieds or recommendations for their next pet projects just to name a few. At the same time, with the latest advances in the area of Machine Learning and AI, the modern search needs to be intelligent, domain-aware, contextual, and personalized. Using these guiding principles, the Search Team at Nextdoor has built modern, AI-Powered Search. In this talk, we will present the search advances we have conducted in the area of Query Understanding, Recall, and Ranking using principles we have listed above.Download the Slides
