Elasticsearch
Distributed search engine with vector support alongside full-text search.
Aperçu
Elasticsearch is a distributed search engine whose primary model is inverted-index text search, with vector search added alongside it. It solves the practical problem that most search is still keyword search, and a system that only does embeddings loses the exact-match behaviour users expect for names and codes. It exists because hybrid retrieval usually beats either approach alone, and running both in one engine avoids synchronising two.
