Here is the algorithm for how we improved search | Algolia

Algolia is a search engine designed for database searches that uses an algorithm to rate each matching record on several criteria, such as the typo count or geo-distance. The ranking algorithm assigns integer value scores to each criterion, allowing users to apply their own criteria and model business logic directly within the search engine. Algolia's approach differs from traditional search engines that primarily rely on counting query words in documents. By using prefix matching, Algolia can return relevant results even when a user has only typed a single letter. The algorithm also allows users to specify additional criteria like custom business metrics and integrate them into the relevance calculation.
