sonic

Fast, lightweight, and schema-less search backend

Sonic is a fast, lightweight, and schema-less search backend. It ingests search texts and identifier tuples that can then be queried against in a microsecond's time. Sonic can be used as a simple alternative to super-heavy and full-featured search backends such as Elasticsearch in some use-cases. It is capable of normalizing natural language search queries, auto-completing a search query and providing the most relevant results for a query. Sonic is an identifier index, rather than a document index; when queried, it returns IDs that can then be used to refer to the matched documents in an external database. A strong attention to performance and code cleanliness has been given when designing Sonic. It aims at being crash-free, super-fast and puts minimum strain on server resources.
