This project is an advanced application using microservice architecture to provide an AI-powered document search and query platform. Users can upload documents to the system and utilize text mining and artificial intelligence technologies for advanced search and question-answering capabilities.

• Document Upload and Processing: Supports PDF, TXT, DOCX, and other document formats
• Automatic OCR: Automatically converts scanned documents and images to text
• Semantic Search: Quickly find relevant documents with meaning-based search
• AI Queries: Ask complex questions based on the content of your documents
• Multi-language Support: Support for multiple languages including Turkish and English
• Secure Access Control: Role-based authorization system

This system has a modular structure that includes the following microservices:

• API Gateway: Receives all client requests and routes them to relevant services
• Document Processing: Document processing, text extraction, and OCR
• Search Service: Full-text search and indexing
• Storage Service: Document storage and metadata management
• Vector Service: Document vector embeddings and semantic search
• Query Engine: Natural language queries and AI responses

• Backend: Node.js, Fastify, gRPC
• Frontend: SvelteKit
• Database: PostgreSQL, Drizzle ORM
• Search Engines: Typesense (text search), Qdrant (vector search)
• Messaging: Apache Kafka
• Storage: MinIO (S3-compatible object storage)
• AI/ML: OpenAI (embeddings, question-answering)

• Node.js 18+
• PostgreSQL
• MinIO (optional, for file storage)
• Apache Kafka (optional, for asynchronous communication)
• Typesense (optional, for full-text search)
• Qdrant (optional, for vector search)
• OpenAI API key (for AI functionality)

1. Clone the project:

   git clone https://github.com/username/intelligent-document-search.git
   cd intelligent-document-search

2. Install dependencies:

   npm install

3. Configure the .env file (copy .env.example for reference)

4. Initialize the database:

   npm run db:push
