🔍Modeler Search Enhancer Plugin

            The Modeler Search Enhancer plugin provides advanced search functionality for QGIS Processing Modeler algorithm inputs and outputs. It enhances ComboBox fields with intelligent filtering capabilities to help you quickly find the algorithm outputs you need.
        

🎯What does this plugin do?

Key Features:

🔍 Smart Search - Adds intelligent search capabilities to Modeler input/output ComboBoxes
⚡ Real-time Filtering - Filters results as you type
🎯 Intelligent Detection - Only enhances relevant ComboBoxes (algorithm inputs/outputs)
🚫 Non-intrusive - Ignores configuration and dependency ComboBoxes
🔤 Case-insensitive - Search works regardless of capitalization
📝 Multi-term Search - Search for multiple words simultaneously

🚀How to use the plugin

Step 1: Open the QGIS Processing Modeler

Step 2: Create or open a model with multiple algorithms

Step 3: When adding a new algorithm, click on any input ComboBox that contains algorithm outputs

Step 4: You'll notice the ComboBox now has:

🟢 Green border indicating it's searchable
🔍 Search placeholder text
✨ Enhanced filtering capabilities

Step 5: Start typing to filter the available options!

🔍 Search Example

Type "buffer" to find all algorithm outputs containing "buffer"

Type "clip merge" to find outputs containing both "clip" AND "merge"

⚙️How it works

The plugin automatically:

Monitors - Continuously monitors for open Modeler windows
Analyzes - Identifies ComboBoxes that contain algorithm outputs
Enhances - Adds search functionality only to relevant ComboBoxes
Filters - Provides real-time filtering based on your input

⚠️ Note: The plugin only enhances ComboBoxes that contain algorithm outputs (like "Result from buffer operation"). It intelligently ignores configuration ComboBoxes such as "Dependencies", parameter dropdowns, and other non-algorithm-output fields.

🎨Visual Indicators

🟢 Green Border: Indicates a ComboBox has been enhanced with search
🔍 Placeholder Text: Shows "🔍 Type to filter..." in enhanced ComboBoxes
💡 Light Green Background: Enhanced ComboBoxes have a subtle green background

🔧Search Capabilities

Search Features:

Partial Matching: Search finds text anywhere in the algorithm name
Multi-word Search: Space-separated terms must all be present
Case Insensitive: "BUFFER", "buffer", and "Buffer" all work the same
Auto-completion: Popup shows filtered results as you type
Smart Selection: Click any result to select it

🛠️Technical Details

The plugin uses advanced Qt widget analysis to:

Identify Modeler dialog windows
Analyze ComboBox content to determine if they contain algorithm outputs
Apply search enhancements only where appropriate
Maintain compatibility with existing Modeler functionality

❓Troubleshooting

If the search doesn't appear:

Make sure you're in a Modeler window with algorithm inputs/outputs
Check that the ComboBox contains algorithm outputs (not just configuration options)
Restart QGIS if the plugin seems unresponsive

📞Support

This plugin enhances your QGIS Modeler workflow by making it easier to find and select algorithm outputs when building complex models. It's particularly useful when working with models that have many algorithms and outputs.

            💡 Tip: The more algorithms in your model, the more useful this plugin becomes! It's designed to scale with model complexity.
