-- **Replicas**: 1 (redundancy)
-- **Analyzer**: Custom lowercase analyzer
+### Key Patterns
+- **Documents**: `hash:plaintext:{plaintext}` - Main document storage
+- **MD5 Index**: `hash:index:md5:{hash}` - MD5 hash lookup
+- **SHA1 Index**: `hash:index:sha1:{hash}` - SHA1 hash lookup
+- **SHA256 Index**: `hash:index:sha256:{hash}` - SHA256 hash lookup
+- **SHA512 Index**: `hash:index:sha512:{hash}` - SHA512 hash lookup
+- **Statistics**: `hash:stats` - Redis Hash with count and size
