parse ios sdk

¿Mi tabla de tabla sintáctica es ineficaz(swift/objectiveC)?

Question

Así que tengo un montón de campos en mi servidor de análisis y tengo una vista de tabla en mi aplicación de iOS. Para cada célula hay un montón de datos como dije antes. Pero el problema es que quiero permitir que un usuario pueda buscar esos datos. Mi pregunta es, si tengo que decir 50,000 pfobjects de listados y mi servidor de parseo y un usuario está buscando en muchos campos, va a ser extremadamente caro o las búsquedas no son tan costosas. Tenga en cuenta que todo lo que busca está en minúscula, por lo que no será un problema. Aquí está mi código. Tengo 31 campos en los que estoy buscando texto. Es malo hacer eso ¿Debo aumentar un montón de facturas en mi lado del servidor si tengo cientos de miles de usuarios? Heres es mi código.

var query : PFQuery<PFObject>!
             query.order(byDescending: "createdAt")
            let fiel1 = PFQuery(className: "Real Estate")
            field1.whereKey("field one", contains: search)
            let field2 = PFQuery(className: "Real Estate")
            field2.whereKey("field two", contains: search)
