Based off the conversation today, null in any required input will lead to a null output
Suggested change
| stringContains(null, "regsvr32") // returns null | |
| stringContains(null, "regsvr32") // returns null | |
| stringContains(process.command_line, null) // returns null |

LGTM.
Suggested, also, another example to add.
| // process.command_line = "start regsvr32.exe" | ||
| stringContains(process.command_line, "regsvr32") // returns true | ||
| stringContains(process.command_line, "start ") // returns true | ||
| stringContains(process.command_line, "explorer") // returns false |

I would add one additional example, to show a less obvious usage: stringContains(process.path, process.name).
