+```go
+// Create context store
+store := NewContextStore(nodeID, localStorage, distributedStorage, 
+    encryptedStorage, cacheManager, indexManager, backupManager, 
+    eventNotifier, options)
+
+// Store a context
+err := store.StoreContext(ctx, contextNode, []string{"developer", "architect"})
+
+// Retrieve a context
+context, err := store.RetrieveContext(ctx, ucxlAddress, "developer")
+
+// Search contexts
+results, err := store.SearchContexts(ctx, &SearchQuery{
+    Query: "authentication system",
+    Tags:  []string{"security", "backend"},
+    Limit: 10,
+})
+```
+
+### Batch Operations
+```go
+// Batch store multiple contexts
+batch := &BatchStoreRequest{
+    Contexts: []*ContextStoreItem{
+        {Context: context1, Roles: []string{"developer"}},
+        {Context: context2, Roles: []string{"architect"}},
+    },
+    Roles: []string{"developer"}, // Default roles
+    FailOnError: false,
+}
+
+result, err := store.BatchStore(ctx, batch)
+```
+
+### Backup Management
+```go
+// Create a backup
+backupConfig := &BackupConfig{
+    Name: "daily-backup",
+    Destination: "/backups/contexts",
+    IncludeIndexes: true,
+    IncludeCache: false,
+    Encryption: true,
+    Retention: 30 * 24 * time.Hour,
+}
+
+backupInfo, err := backupManager.CreateBackup(ctx, backupConfig)
+
+// Schedule automatic backups
+schedule := &BackupSchedule{
+    ID: "daily-schedule",
+    Name: "Daily Backup",
+    Cron: "0 2 * * *", // Daily at 2 AM
+    BackupConfig: backupConfig,
+    Enabled: true,
+}

+- **Search operations**: 5-20ms latency (index size dependent)
+
+### Scalability
+- **Horizontal scaling**: Linear scaling with additional nodes
+- **Storage capacity**: Petabyte-scale with proper cluster sizing

+- **Search performance**: Sub-second for most queries
+
+### Resource Usage
+- **Memory**: Configurable cache sizes, typically 1-8GB per node
