How can I search multiple fields from the same collection?

Attempted to do it this way but it did not work

settings: function() {
        return {
            position: 'bottom',
            limit: 5,
            rules: [
                 {
                     collection: Models,
                     field: 'name',
                     matchAll: true,
                     template: Template.standardLegends,
                },
                {
                    collection: Models,
                    field: 'createdBy',
                    matchAll: true,
                    template: Template.standardLegendsOwner,
                },
            ],
        };
    },

However this doesn't work. Is there any way to accomplish this?
