Description
Pure function returning true if text contains search.
When to use
Use String contains? to check whether a substring is present anywhere in a string before branching or filtering. The search is case-sensitive — apply Lowercase to both inputs first if a case-insensitive check is needed. Connect the boolean result directly to a Branch condition input to control execution flow.
Pins
Input pins
| Pin | Type | Default | Notes |
|---|---|---|---|
| Text | string | — | The string to search within. The check is case-sensitive. |
| Search | string | — | The literal substring to look for. The empty string always matches. |
Output pins
| Pin | Type | Notes |
|---|---|---|
| Result | boolean | True if search appears anywhere in text; false otherwise. |
Example
Skip processing if an email address is from a blocked domain. Wire the email string
into the Text input of String contains? with Search set to "@blocked.com", then
connect the Result output to the Condition input of Branch. The True execution output
routes to Fail; otherwise execution continues past the branch.
