Rag.NET.VectorStores.PgVector

PostgreSQL + pgvector vector store for Rag.NET: dense cosine search over a vector column, with optional learned sparse vectors (SPLADE-style) for hybrid retrieval — your RAG index lives in the database you already run.

Install

dotnet add package Rag.NET.VectorStores.PgVector

Install alongside the core pipeline package (dotnet add package Rag.NET), which supplies the AddRagNet(...) builder the store registers into.

Setup

Inside your AddRagNet(...) builder callback:

using Rag.NET.PgVector;

rag.UsePgVector(
    connectionString: "Host=localhost;Database=ragdb;Username=postgres;Password=secret",
    vectorDimensions: 1536);

Example

Create the table and indexes once at startup, then ingest as usual:

using Microsoft.Extensions.DependencyInjection;
using Rag.NET.Abstractions;
using Rag.NET.PgVector;

var store = provider.GetRequiredService<IVectorStore>() as PgVectorStore;
await store!.InitializeAsync();

Hybrid dense + learned-sparse search stores both vector kinds side by side:

rag.UsePgVector(
    connectionString:     "Host=localhost;Database=ragdb;Username=postgres;Password=secret",
    vectorDimensions:     1536,
    enableSparseVectors:  true,
    sparseVocabularySize: PgVectorSparseVectorStore.DefaultSparseVocabularySize); // 30522
