        .addAnd('date', 'greaterThan', '2018-07-04')
        .addOr('topNews', 'equal', true)
        /** filter by document id **/

        /** filter blogPosts (contentType) by title **/
        .addAnd('title', 'like', '%Hello%', 'fields', 'blogPosts')
        
        // syntax
        // .addAnd(property: string(<id|title|...>), operator: string(<equals|like|...>), value: any, context: string(<fields|meta>), contentType: string(<*|contentTypeApiId>))
        // .addOr(property: string(<id|title|...>), operator: string(<equals|like|...>)), value: any, context: string(<fields|meta>), contentType: string(<*|contentTypeApiId>))
