Multiple Validation Keywords work in JSON Schema with the "AND" logic. The order of validation keywords is not important. In other words, all of them are applied individually to the JSON instance based their specified conditions.

JSON Schema: 
{
    "pattern": ".*@.*",
    "type": "string",
	"minLength": 15
}

{"enum": ["YES", "NO"]}

Valid JSON instance:

Invalid JSON instance:
"to@bbc.com"

Invalid JSON instance:
