 # Build a .NET AI vector search app
 
-In this quickstart, you create a .NET console app to perform semantic search on a vector store to find relevant results for the user's query. You learn how to generate embeddings for user prompts and use those embeddings to query the vector data store. Vector search functionality is also a key component for Retrieval Augmented Generation (RAG) scenarios. The app uses the <xref:Microsoft.Extensions.AI> and [Microsoft.Extensions.VectorData.Abstractions](https://www.nuget.org/packages/Microsoft.Extensions.VectorData.Abstractions) libraries so you can write code using AI abstractions rather than a specific SDK. AI abstractions help create loosely coupled code that allows you to change the underlying AI model with minimal app changes.
+In this quickstart, you create a .NET console app to perform semantic search on a _vector store_ to find relevant results for the user's query. You learn how to generate embeddings for user prompts and use those embeddings to query the vector data store.

+Vector stores, or vector databases, are essential for tasks like semantic search, retrieval augmented generation (RAG), and other scenarios that require grounding generative AI responses. While relational databases and document databases are optimized for structured and semi-structured data, vector databases are built to efficiently store, index, and manage data represented as embedding vectors. As a result, the indexing and search algorithms used by vector databases are optimized to efficiently retrieve data that can be used downstream in your applications.

-- Generate an embedding for the user prompt
-- Query the vector store using the user prompt embedding
-- Display the relevant results from the vector search
