Gone are the days of analyzing spreadsheets of low-performing queries. Let the machine handle curation tasks by learning from the behavior of your customers and the content of your catalog. Query Rewriting uses ML to suggest synonyms, phrases, and spelling corrections. Each suggestion includes a confidence score, making it easier for search owners to select a subset of high-confidence suggestions for approval. Head-Tail Analysis compares low-performing tail queries with performant head queries, and suggests rewrites accordingly.
