Neo4j has introduced native vector search, enabling customers to uncover hidden relationships and achieve richer insights from generative AI applications. This capability allows teams to use vector search to understand the meaning behind words rather than matching keywords, providing a simple approach for quickly finding contextually related information. Vector search can be used in combination with knowledge graphs to improve the accuracy of responses by grounding large language models (LLMs) with relevant information about the answers before they create and return a response. This combination provides users with the most relevant and contextually accurate responses, improving the accuracy of enterprise-wide applications and use cases such as enhanced fraud detection, personalized recommendations, and discovery of new answers. Neo4j's vector search allows users to create a vector index that performs fast approximate k-nearest neighbor searches using either cosine or euclidean similarity, enabling businesses to see promising results in reducing time and improving efficiency across sectors.
