How to use the filter

import { QueryGenerator } from 'graphql-elasticsearch';

let args = {email:'[email protected]'};  // Graphql query args
const testFilterConfig: any  = {
    filter: {
        isNull: ['id'],
        isNotNull: ['email'],
        arguments: {
            id: {
                description: 'Unique Identifier',
                db_field_name: 'id',
                db_type: 'keyword',
                type: 'string'
            },
            email: {
                description:
                    'This endpoint takes a contact (email) and returns all link documents for that contact.',
                db_field_name: 'email.raw',
                db_type: 'keyword',
                type: 'string'
            },
            and: {
                description: 'AND operator',
                db_field_name: 'None',
                db_type: 'None',
                type: 'array'
            },

                db_type: 'None',
                type: 'array'
            },
            not: {

                db_field_name: 'None',
                db_type: 'None',

                db_field_name: 'None',
                db_type: 'None',
                type: 'string'
            },
            isNull: {
                description: 'field name is null',
                db_field_name: 'None',
                db_type: 'None',
                type: 'string'
            }
        }
    }
