Includes

The Includes node checks if one string includes another string and outputs a boolean result.

​
Inputs

  1. a (string): The string to search within. This is the string that may contain the substring you are looking for.
  2. b (string): The substring to search for. This is the string that you want to check if it is included in the a input.

​
Outputs

  1. result (boolean): Returns true if string a includes string b, otherwise returns false.

​
Configuration

This node has no additional configuration options.

​
Usage

To use the Includes node:
  1. Connect a string to the a input. This is the string you want to search within.
  2. Connect a string to the b input. This is the substring you want to check for inclusion in a.
  3. The result output will emit true if b is found within a, otherwise it will emit false.

​
Example

Let’s say you have a spell that processes customer feedback messages. You want to check if each message includes the word “great” and keep a count of the positive messages. You could use the Includes node like this:
  1. Connect the customer message string to the a input.
  2. Connect a Constant node with the value “great” to the b input.
  3. Connect the result output to a Filter node to only pass through messages where result is true.
  4. Connect the filtered messages to a Count node to keep a running total of positive messages.
In this example, the Includes node allows you to easily check each message for specific positive keywords and filter the messages accordingly for further aggregation.

​
Best Practices

  • Make sure the input types match. Both inputs should be strings.
  • The search is case-sensitive. Use a Transform node beforehand to convert the strings to a consistent case if needed.
  • If you need to check for multiple substrings, you can chain multiple Includes nodes together with OR logic for more complex checks.

​
Common Issues

  • Passing a non-string value to either input will cause an error. Ensure you are passing strings.
  • An empty string input for b will always return true since technically an empty string is included in every string. Check your logic if you get unexpected true results.
