πŸ“‹ Complete Case Study: Building a Minimal AI Search Engine

Task: Create a Basic Perplexica Clone in 2 Hours

Goal: Build a working AI search engine with query processing, web search, semantic reranking, and streaming answers.

Tech Stack: Next.js + LangChain + OpenAI + SearXNG (Docker)


πŸ“œ Phase 1: Project Setup and Architecture

Setup Prompt
"You are SearchArchitectGPT. Help me build a minimal AI search engine inspired by Perplexica.
 
PROJECT REQUIREMENTS:
- Next.js 14 with TypeScript and Tailwind CSS
- LangChain for AI orchestration
- OpenAI for LLM and embeddings
- SearXNG for meta-search (Docker)
- Streaming responses with citations
- Semantic result reranking
 
ARCHITECTURE GOALS:
1. Query processing with context awareness
2. SearXNG integration for web search
3. Embedding-based result reranking
4. Streaming answer generation with citations
5. Simple, clean UI with real-time updates
 
TASKS:
1. Set up Next.js project with required dependencies
2. Create docker-compose.yml for SearXNG
3. Build basic project structure:
   - /app/api/search/route.ts (main search endpoint)
   - /lib/search.ts (search logic)
   - /lib/rerank.ts (semantic reranking)
   - /components/SearchInterface.tsx (UI)
   - /components/StreamingAnswer.tsx (real-time display)
 
OUTPUT: Complete file structure and package.json with exact dependencies needed."

πŸ“œ Phase 2: Search Logic Implementation

Search Logic Prompt
"You are SearchLogicGPT. Build the core search functionality for my AI search engine.
 
CONTEXT: Next.js app with LangChain, OpenAI, and SearXNG running on localhost:4000
 
REQUIREMENTS:
1. Query processing chain that:
   - Analyzes conversation history for context
   - Determines if web search is needed (skip for greetings)
   - Optimizes natural language queries for search engines
   - Handles both general queries and direct URL processing
 
2. SearXNG integration that:
   - Sends optimized queries to localhost:4000/search
   - Handles different search engines (web, academic, images)
   - Processes results into clean, structured format
   - Extracts titles, URLs, and content snippets
 
3. Basic semantic reranking that:
   - Converts query and results to embeddings
   - Calculates cosine similarity scores
   - Filters results below 0.3 relevance threshold
   - Returns top 10 most relevant results
 
IMPLEMENTATION FILES NEEDED:
- /lib/search.ts (main search orchestration)
- /lib/searxng.ts (SearXNG API client)
- /lib/rerank.ts (embedding and similarity logic)
- /app/api/search/route.ts (API endpoint)
 
OUTPUT: Complete TypeScript implementations with proper error handling and types."

πŸ“œ Phase 3: Streaming Answer Generation

Answer Generation Prompt
"You are AnswerStreamGPT. Implement streaming AI answer generation with citations.
 
CONTEXT: Search results are ready, now need to generate streaming answers with source citations.
 
REQUIREMENTS:
1. LangChain streaming setup:
   - Create chat prompt template with system instructions
   - Include search results as numbered context
   - Stream responses token by token to frontend
   - Handle streaming events and error states
 
2. Citation system:
   - Format search results as numbered sources [1], [2], [3]
   - Instruct AI to cite every statement with numbers
   - Track which sources are used in the response
   - Display clickable source links below answers
 
3. Response quality controls:
   - Professional, journalistic tone
   - Clear structure with headings
   - Comprehensive coverage of the topic
   - Conclusion that synthesizes information
 
IMPLEMENTATION FILES:
- /lib/generate.ts (streaming answer generation)
- /app/api/chat/route.ts (streaming endpoint)
- /components/StreamingAnswer.tsx (real-time UI)
- /components/SourceCitations.tsx (citation display)
 
PROMPT TEMPLATE REQUIREMENTS:
- Role: Expert research assistant
- Format: Markdown with headings
- Citations: [number] notation for every fact
- Length: Comprehensive but not excessive
- Sources: Always show numbered source list
 
OUTPUT: Complete streaming implementation with citation management."

πŸ“œ Phase 4: Advanced Features Integration
