Data is the lifeblood of modern analysis and decision-making. Raw data streams from APIs, databases, and feeds often need refinement before they become actionable insights. Introducing the Sort & Filter worker - your essential tool for transforming unstructured data into organized, analysis-ready information.

What is Sort & Filter?

The Sort & Filter worker is a powerful data transformation tool that lets you refine, organize, and structure your data with precision. Whether you're working with financial market data, news feeds, API responses, or any structured data, this worker gives you complete control over how your information is processed and presented.

From filtering out irrelevant records to sorting by importance and selecting only the fields you need, Sort & Filter acts as the bridge between raw data collection and meaningful analysis.

Key Features

  • Advanced Filtering: Apply multiple conditions with AND/OR logic to find exactly the data you need
  • Intelligent Sorting: Organize data by any field in ascending or descending order
  • Column Selection: Keep only relevant fields and remove unnecessary data
  • Result Limiting: Control output size for better performance and focus
  • Smart Search: Find text matches using fuzzy similarity for flexible content discovery
  • Expression Support: Use dynamic expressions to create custom filtering logic
  • Real-time Processing: Handle large datasets efficiently without performance degradation

How It Works

  • Combine category and source filtering for precise content control
  • Limit results appropriately for your processing capacity

Date Range Strategies

  • Use ISO format (YYYY-MM-DD) for all date parameters
  • Omit dateTo for ongoing "breaking news" monitoring
  • Use dateFrom only for "from this date forward" queries

Performance Considerations

  • Lower limits (50-100) for real-time applications
