What are Elasticsearch and Marqo?
Elasticsearch
Elasticsearch is a distributed, RESTful search and analytics engine capable of addressing a wide variety of use cases. It stores and indexes large volumes of data for fast full-text and structured search.
- Distributed full-text search
- Aggregations and analytics
- Horizontal scalability
- Rich query DSL
Marqo
Marqo is an open-source, end-to-end search engine that combines vector generation, storage and retrieval. It handles embedding creation automatically so you can run semantic search over text and images.
- Built-in embedding generation
- Text and image semantic search
- No separate ML pipeline needed
- Simple REST API
