Enterprise Search Relevance at Box: Simplicity
Jay Franck • Location: Theater 5 • Back to Haystack 2023
At Box, we serve millions of users across many thousands of enterprises. The set of enterprises served span the scale from startups and non-profits to some of the largest corporations in the world. The documents in each enterprise are in different languages and media types, and require the strongest privacy and security controls. How do we deliver relevant search results, across such a diverse set of users, cultures, and documents in a scalable way? How do we preserve the privacy and security for our customers? This talk will focus on our current solution: a Solr search engine and a Tensorflow Ranking model to rerank the Top K results per query. Over the years, we have tuned our Solr query parameters using a mix of heuristics, data analysis and genetic algorithms. From this initial set of documents that could be returned to the user, we extract a number of numeric and binary features, add in recency information, and feed this into our global reranking algorithm.Watch the Video
