| IN | The operator expects a list of the elements on the right side.  The API supports a single string as the value on the right side of the  operator so we follow a convention when you can provide multiple values  in a single string by separating them with a '~~' string. |

| NOT_REGEX | An inversion of a regex. |
| WILDCARD | A simplified regex syntax, where '*' is the wildcard character and '?'  matches a single character and there are no other special characters.   Matches are always made against the entire string. |
| NOT_WILDCARD | A negation of the WILDCARD operator. |
| SET | The operator doesn't expect any value on the right side.  Matches if a value of a given field is set. |
| NOT_SET | The operator doesn't expect any value on the right side.  An inversion of a "SET" operator. |
