For each trigger

Type: For each | Category: Trigger | Icon: 🔁

The For each trigger iterates over a collection (array, list, or enumerable) and triggers connected child operations once per item. This is essential when an HTTP response or script returns multiple results that each need their own processing.

This trigger is used mid-flow (connected after another operation) — it takes the previous operation's result (or a specified variable) and loops over it.

Settings

Setting Type Default Description
Input Variable string "" The variable name containing the array to iterate. Leave empty to use the last operation's result directly. Can be a C# expression

Outputs

Each iteration outputs the current item as an object.

Default variable mappings

Variable Name Expression Description
item result The current item in the iteration

Examples

Display multiple HTTP results

  1. Search trigger → HTTP Action (fetches a JSON array of results)
  2. Parse JSON → creates json variable
  3. For each with Input Variable: json (or empty to use last result)
  4. Custom result → Name = "{item["title"]}", Context = "{item["url"]}"

Each item in the JSON array creates a separate search result in the Fluent Search UI.

Process each line of a file

  1. Hotkey trigger → Read file text → C# Script: return fileContent.Split('\n');
  2. For each (iterates over each line)
  3. Custom result showing each line

Tips

  • For each supports any IEnumerable — arrays, lists, LINQ results, and split strings all work.
  • Keep the loop body lightweight for large collections — avoid HTTP calls inside For each loops (fetch all data first, then iterate).
  • The iteration respects cancellation — if the user starts a new search, the loop stops.
  • Combine with Condition nodes inside the loop body to filter items.
