When to use¶
Classification: process.
Tagged: boolean, match, prefix, process, scalar, starts_with, string, text.

| Haystack | haystack | scalar | — | ✓ | The full string to inspect; provide any scalar text value that you want to test for a leading substring. |
| Needle | needle | scalar | — | ✓ | The prefix substring to look for at the start of the haystack; treated as a literal string (quote=1). |
Outputs¶
