Smart Search – Advanced Hierarchy Filtering

Smart Search transforms Unity's basic hierarchy search into a powerful filtering system with visual query builder, logical operators, and instant results. Perfect for large scenes, complex prefabs, and productivity-focused developers.

🎯 Why Smart Search?

Working on a scene with hundreds of GameObjects? Need to find all enemies with Rigidbody on a specific layer? Want to batch-edit objects with certain component values?

Unity's built-in search falls short. Smart Search fills the gap with:

• ✅ Visual Query Builder - No typing complex queries, just click and select
• ✅ Component Field Filtering - Search by component property values (health > 50, speed <= 10)
• ✅ Logical Operators - Combine filters with AND, OR, NOT
• ✅ Multiple Result Actions - Select, Highlight, or Filter View with one click
• ✅ Preset System - Save and reuse common searches instantly
• ✅ Zero Learning Curve - Intuitive interface, start using in 30 seconds

🚀 Key Features

Visual Query Builder

Build complex searches without typing a single query string:

• Dropdown selection for all filter types
• Auto-complete component search
• Public field/property dropdown for component filtering
• Add/remove conditions with single clicks
• Real-time feedback as you build

Powerful Filtering Options

• Name - Contains, exact, starts/ends with matching
• Tag - Select from project tags
• Layer - Select from project layers
• Component - Search by component existence OR field values
• Static Flag - Find static/non-static objects
• Active State - Find active/inactive objects
• Logical Operators - AND, OR, NOT between any filters

Component Field Search

Component: Player

Field: health

Comparison: >

Value: 50

Finds all Player components where health is greater than 50. Works with:

• Int, Float, Bool, String fields
• Public properties
• Any comparison operator (=, !=, >, <, >=, <=)

Four Result Actions

Select All - Select all matching objects for batch editing

Select Inverse - Select everything EXCEPT matches

Highlight - Blue highlight in hierarchy (non-intrusive)

Filter View - Hide non-matching objects (like Unity's native search)

Smart Preset System

• Save frequently used searches as reusable presets
• One-click application from preset library
• Update existing presets anytime
• Lightweight ScriptableObject assets
• Perfect for team workflows

💼 Perfect For

Level Designers

• Find all trigger colliders in specific areas
• Locate all lights on environment layer
• Batch-edit spawn points and waypoints
• Filter decoration objects by type

Technical Artists

• Find all renderers on specific layers
• Locate objects with certain materials
• Batch-process LOD groups
• Optimize scene rendering

Teams

• Share preset libraries across team

🎨 Workflow Examples

Example 1: Find All Enemies with AI

Component: Enemy

AND Component: NavMeshAgent

AND Tag: Enemy

AND Layer: Default

One search, perfect results. Select All → Batch edit properties.

Example 2: Debug Low Health Players

Component: PlayerHealth

Field: currentHealth

Comparison: <

Value: 30

Instantly find all players in critical health state.

Example 3: Cleanup Scene

Name: Test

OR Name: Debug

OR Active: False

Find all test/debug objects and inactive GameObjects. Delete in one go.

Example 4: Optimize Rendering

Component: MeshRenderer

AND Layer: Environment

AND Static: True

Find all static environment renderers. Batch lightmap settings.
