Vector Search for LLM and Generative AI Applications
Unlock the power of semantic search for real-time and generative AI with Astra DB and Apache Cassandra®
What is Vector Search?
Vector search is an advanced approach to data retrieval used in machine learning and generative AI, that focuses on semantic meaning and similarity rather than specific keywords. By representing data as vectors in a high-dimensional space, it enables more accurate and intuitive search results.
Build Generative AI and LLM Apps
Vector search enables AI and machine learning practitioners to build innovative Generative AI applications and LLM agents on Cassandra.
Use Real-time NoSQL data for Unique AI Results
Vector search with Apache Cassandra and Astra DB allows querying of large volumes of unstructured data like text, audio, images, and videos, supporting many use cases and adding to Cassandra's and Astra’s capabilities as a high-scale database. It enhances search accuracy by considering semantic meaning and uncovers hidden relationships and patterns.
Vector search for Astra DB and Cassandra handles large-scale similarity queries and query processing efficiently within the database, eliminating the need to transfer large amounts of data and improving performance.
Integrate Vector Search into Applications
Vector search is particularly useful in generative AI applications for question answering, semantic search, and semantic caching. CassIO, an open source software framework, facilitates the integration of vector search into applications.
What are some Potential Vector Search Use Cases?
While vector search is at the foundation of LLM-powered applications, it is also being used for uses cases beyond just generative AI.
Question-Answering Systems:

How does Vector Search Work?
Vector search leverages vector similarity calculations and semantic meaning to provide an innovative approach to data retrieval, leveraging:
Vector Representation
Data points are represented as vectors, which capture the characteristics and features of the data in a high-dimensional space.
Similarity Calculation
Vector search employs advanced algorithms to calculate the similarity between vectors. It measures the angle or distance between vectors to determine their level of similarity.
Semantic Meaning
Unlike traditional keyword-based searches, vector search focuses on the semantic meaning and context of the data points. It captures the inherent relationships and patterns within the data, allowing for more accurate search results.
High-Dimensional Space
Vectors are placed in a high-dimensional space, where each dimension represents a unique feature or attribute of the data. This arrangement enables vector search to identify complex relationships and similarities.
Efficient Indexing
Vector search employs efficient indexing techniques, such as approximate nearest neighbor (ANN) algorithms, to quickly find the most similar vectors without exhaustively comparing every vector in the dataset.
Query Processing
Vector search performs similarity calculations directly within the database, eliminating the need to transfer large amounts of data. This improves query processing speed and reduces latency.
Scalability
Vector search is suitable for handling large datasets, leveraging distributed computing frameworks to process similarity queries efficiently across multiple nodes.
Data Types
Vector search can be applied to text, numerical values, images, and embeddings, enabling developers to build applications that span different domains.
Vector search revolutionizes data retrieval by considering semantic meaning, employing efficient indexing techniques, and leveraging the power of high-dimensional vector representations. It enables accurate and efficient search results across diverse datasets.
