What is Elasticsearch's vector database?

Elasticsearch's vector database is a powerful tool that allows you to efficiently create, store, and search vector embeddings at scale. By combining text search and vector search capabilities, it provides enhanced relevance and accuracy for your retrieval needs.

Key Features:

1. Vector Storage: Elasticsearch's vector storage is based on Lucene's HNSW algorithm, which performs well in benchmarks for vector search algorithms.

2. Hybrid Retrieval: With hybrid retrieval, you can choose from a combination of retrieval methods such as BM25, trained sparse models (ELSER), and dense vectors to optimize your search results.

3. Document Security & Compliance: Elasticsearch offers granular role-based access controls with document and field level security to ensure compliance with various frameworks.

Use Cases:

1. Semantic Search: Use the vector database for semantic search applications where you want to focus on intent and contextual meaning beyond simple text matching.

2. Multi-modal Search: Perform comprehensive searches across different types of data including text, vectors, images, audio, video, geo-location information or unstructured data.

3. AI-powered Search Experience: Augment your retrieval capabilities with machine learning techniques for an advanced GAI (Generative AI) search experience using vectors and hybrid relevance.

Conclusion:

Elasticsearch's vector database empowers users to create efficient searches by leveraging the power of vectors while maintaining compatibility with traditional text-based searching methods. With its robust features like hybrid retrieval and document-level security controls, this tool enables developers to build sophisticated applications that deliver accurate results across diverse datasets. Whether it's semantic search or multi-modal exploration of data sources - Elasticsearch has got you covered!
