What are bleve and Marqo?
bleve
An embeddable modern full-text search and indexing library that lets developers add search to applications without running a separate server. It supports analyzers, faceting, and scoring out of the box.
- Embeddable index
- Text analyzers
- Faceted search
- Pluggable storage
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
