# Filter

Remove data items matching conditions.

## Overview

The Filter node allows you to define conditions, and when the data items match these conditions, they will be removed from the workflow.

## Usage
1. Add the Filter node to your workflow in Suger.
2. Configure conditions to evaluate incoming data.
3. Connect downstream node to the output of this node.
4. Save and activate the workflow.

## Configuration

### Add Conditions
- **Data Type**: Select the type (e.g., String, Number, Date) for comparison.
- **Comparison**: Choose an operation (e.g., `is equal to`, `is greater than`).
- **Value**: Enter the value to compare against.
- **Combination**: Use `AND` or `OR` to combine multiple conditions.

### Options
- **Ignore Case**: Toggle to make string comparisons case-insensitive.
- **Less Strict Type Validation**: Toggle to allow flexible type matching (e.g., comparing a string "123" to a number 123).
