EasyAppDev.Blazor.AutoComplete.AI.PostgreSql

PostgreSQL/pgvector integration for semantic search with the Blazor AutoComplete component.

👁 NuGet
👁 License: MIT

Features

  • pgvector Support: Native PostgreSQL vector similarity search
  • 6 Distance Functions: Cosine, L2, DotProduct + 3 pgvector-only
  • HNSW Index: High-performance approximate nearest neighbor search
  • Self-Hosted: Full control over your data and infrastructure

Installation

dotnet add package EasyAppDev.Blazor.AutoComplete.AI.PostgreSql

Prerequisites

  1. PostgreSQL 15+ with pgvector extension:
CREATE EXTENSION vector;

Quick Start

1. Configure Services

// Program.cs
builder.Services.AddAutoCompletePostgreSql<Product>(
 connectionString: "Host=localhost;Database=myapp;Username=user;Password=pass",
 options => {
 options.TableName = "product_embeddings";
 options.Dimensions = 1536;
 options.DistanceFunction = DistanceFunction.Cosine;
 },
 textSelector: p => $"{p.Name} {p.Description}",
 idSelector: p => p.Id.ToString());

// Register embedding generator
builder.Services.AddAutoCompleteVectorSearch<Product>(
 openAiApiKey: "sk-...");

2. Use the Component

@using EasyAppDev.Blazor.AutoComplete.AI

<VectorAutoComplete TItem="Product"
 TextField="@(p => p.Name)"
 @bind-Value="@selectedProduct"
 Placeholder="Semantic search..." />

Configuration Options

Option Description Default
ConnectionString PostgreSQL connection string Required
TableName Table for embeddings {type}_embeddings
Dimensions Vector dimensions 1536
DistanceFunction Similarity metric Cosine
CreateTableIfNotExists Auto-create table true
UseHnswIndex Enable HNSW index true

Distance Functions

Function Use Case
Cosine Normalized embeddings (default)
L2 Euclidean distance
DotProduct Inner product similarity
L1 Manhattan distance
Hamming Binary vectors
Jaccard Set similarity

Indexing Data

@inject IVectorIndexer<Product> indexer

// Index all products
await indexer.IndexAsync(products);

// Re-index on update
await indexer.UpdateAsync(updatedProduct);
