-## [2.0.0] - 2025-12-03
-
-### Changed
-
-#### Major Backend Migration
-- **Breaking Change**: Migrated from Elasticsearch to Redis for improved performance
-- Replaced Elasticsearch Client with ioredis for Redis operations
-- Redesigned data structure using Redis key patterns
-- Implemented O(1) hash lookups using Redis indexes
-- Significantly reduced search latency (< 10ms typical)
-
-#### New Redis Architecture
-- Document storage: `hash:plaintext:{plaintext}` keys
-- Hash indexes: `hash:index:{algorithm}:{hash}` for fast lookups
-- Statistics tracking: `hash:stats` Redis Hash
-- Pipeline operations for atomic batch writes
-- Connection pooling with automatic retry strategy
-
-### Updated
-
-#### Configuration
-- Environment variables changed from `ELASTICSEARCH_NODE` to `REDIS_HOST`, `REDIS_PORT`, `REDIS_PASSWORD`, `REDIS_DB`
-- Simplified connection setup with sensible defaults
-- Optional Redis authentication support
-
-#### Performance Improvements
-- Search latency reduced to < 10ms (from ~50ms)
-- Bulk indexing maintained at 1000-5000 docs/sec
-- Lower memory footprint
-- Better concurrent request handling (100+ users)

-# Redis Migration - Quick Reference
-
-## 🚀 Quick Start
-
-### 1. Install Redis
-```bash
-# Ubuntu/Debian
-sudo apt-get install redis-server
-
-# macOS
-brew install redis
-
-# Start Redis
-redis-server
-# or
-sudo systemctl start redis-server
-```
-
-### 2. Configure Environment (Optional)
-```bash
-# Create .env.local
-cat > .env.local << EOF
-REDIS_HOST=localhost
-REDIS_PORT=6379
-REDIS_PASSWORD=  # Leave empty if no password
-REDIS_DB=0
-EOF
-```
-
-### 3. Start Application
-```bash
-yarn dev
-```
-
-## 🔍 Testing the Migration
-
-### Test Health Endpoint
-```bash
-curl http://localhost:3000/api/health
-```
-
-Expected response:
-```json
-{
-  "status": "ok",
-  "redis": {
-    "version": "7.x",
-    "memory": "1.5M",
-    "dbSize": 0
-  },
-  "stats": {
-    "count": 0,
-    "size": 0
-  }
-}
-```
-
-### Test Search API
-```bash
-# Generate hashes
-curl -X POST http://localhost:3000/api/search \
-  -H "Content-Type: application/json" \
-  -d '{"query":"password"}'
-
-# Search for hash
-curl -X POST http://localhost:3000/api/search \
-  -H "Content-Type: application/json" \
-  -d '{"query":"5f4dcc3b5aa765d61d8327deb882cf99"}'
-```
-
-## 📊 Redis Commands
-
-### Check Connection
-```bash
-redis-cli ping
-# Should return: PONG
-```
-
-### View Data
-```bash
-# Count all keys
-redis-cli DBSIZE
-
-# List all documents
-redis-cli KEYS "hash:plaintext:*"
-
-# Get a specific document
-redis-cli GET "hash:plaintext:password"
-
-# Get statistics
-redis-cli HGETALL hash:stats
-
-# Search by hash
-redis-cli GET "hash:index:md5:5f4dcc3b5aa765d61d8327deb882cf99"
-```
-
-### Clear Data (if needed)
-```bash
-# WARNING: Deletes ALL data in current database
-redis-cli FLUSHDB
-```
-
-## 🔄 Bulk Indexing
-
-### Basic Usage
-```bash
-yarn index-file sample-wordlist.txt
-```
-
-### Advanced Options
-```bash
-# Custom batch size
-yarn index-file wordlist.txt -- --batch-size 500
-
-# Skip duplicate checking (faster)
-yarn index-file wordlist.txt -- --no-check
-
-# Resume from previous state
-yarn index-file wordlist.txt -- --resume
-
-# Custom state file
-yarn index-file wordlist.txt -- --state-file .my-state.json
-```
-
-## 🐛 Troubleshooting
-
-### Cannot connect to Redis
-```bash
-# Check if Redis is running
-redis-cli ping
-
-# Check Redis status
-sudo systemctl status redis-server
-
-# View Redis logs
-sudo journalctl -u redis-server -f
-```
-
-### Application shows Redis errors
-1. Verify Redis is running: `redis-cli ping`
-2. Check environment variables in `.env.local`
-3. Check firewall rules if Redis is on another machine
-4. Verify Redis password if authentication is enabled
-
-### Clear stale state files
-```bash
-rm -f .indexer-state-*.json
-```
-
-## 📈 Monitoring
-
-### Redis Memory Usage
-```bash
-redis-cli INFO memory
-```
-
-### Redis Stats
-```bash
-redis-cli INFO stats
-```
-
-### Application Stats
-```bash
-curl http://localhost:3000/api/health | jq .
-```
-
-## 🔒 Security (Production)
-
-### Enable Redis Authentication
-```bash
-# Edit redis.conf
-sudo nano /etc/redis/redis.conf
-
-# Add/uncomment:
-requirepass your-strong-password
-
-# Restart Redis
-sudo systemctl restart redis-server
-```
-
-### Update .env.local
-```env
-REDIS_PASSWORD=your-strong-password
-```

-## 📚 Key Differences from Elasticsearch
-
-| Feature | Elasticsearch | Redis |
-|---------|--------------|-------|
-| Data Model | Document-based | Key-value |
-| Search Complexity | O(log n) | O(1) |
-| Setup | Complex cluster | Single instance |
-| Memory | Higher | Lower |
-| Latency | ~50ms | <10ms |
-| Scaling | Shards/Replicas | Cluster/Sentinel |
-
-## ✅ Verification Checklist
-
-- [ ] Redis is installed and running
-- [ ] Application builds without errors (`yarn build`)
-- [ ] Health endpoint returns OK status
-- [ ] Can generate hashes from plaintext
-- [ ] Can search for generated hashes
-- [ ] Statistics display on homepage
-- [ ] Bulk indexing script works
-- [ ] Data persists after application restart

-**Quick Test Command:**
-```bash
-# One-liner to test everything
-redis-cli ping && yarn build && curl -s http://localhost:3000/api/health | jq .status
