我的parsingtableviewsearch效率低下（swift / objectiveC）？

所以我有一堆字段在我的parsing服务器，我有我的iOS应用程序中的tableview。 每个单元格都有一堆数据，就像我之前说过的那样。 但问题是我想让用户能够search这些数据。 我的问题是，如果我可以说5万pfobjects列表和我的parsing服务器，并且一个用户正在寻找这个很多领域，是非常昂贵的或是search不是那么昂贵。 请记住，所有search的内容都是小写的，所以不会成为问题。 这是我的代码。 我有31个字段正在search文本。 这是不好做的。 如果我有成千上万的用户，它会在服务器端增加很多账单吗？ 这是我的代码。

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) let field3 = PFQuery(className: "Real Estate") field3.whereKey("field three", contains: search) let field4 = PFQuery(className: "Real Estate") field3.whereKey("field four", contains: search) let field5 = PFQuery(className: "Real Estate") field5.whereKey("field 5", contains: search) let field6 = PFQuery(className: "Real Estate") field6.whereKey("field 6", contains: search) let field7 = PFQuery(className: "Real Estate") field7.whereKey("field 7", contains: search) let field8 = PFQuery(className: "Real Estate") field8.whereKey("field 8", contains: search) let field9 = PFQuery(className: "Real Estate") field9.whereKey("field 9", contains: search) let field10 = PFQuery(className: "Real Estate") field10.whereKey("field 10", contains: search) let field11 = PFQuery(className: "Real Estate") field11.whereKey("field 11", contains: search) let field12 = PFQuery(className: "Real Estate") field12.whereKey("field 12", contains: search) let field13 = PFQuery(className: "Real Estate") field13.whereKey("field 13", contains: search) let field14 = PFQuery(className: "Real Estate") field14.whereKey("field 14", contains: search) let field15 = PFQuery(className: "Real Estate") field15.whereKey("field 15", contains: search) let field16 = PFQuery(className: "Real Estate") field16.whereKey("field 16", contains: search) let field17 = PFQuery(className: "Real Estate") field17.whereKey("field 17", contains: search) let field18 = PFQuery(className: "Real Estate") field18.whereKey("field 18", contains: search) let field19 = PFQuery(className: "Real Estate") field19.whereKey("field 19", contains: search) let field20 = PFQuery(className: "Real Estate") field20.whereKey("field 20", contains: search) let field21 = PFQuery(className: "Real Estate") field21.whereKey("field 21", contains: search) let field22 = PFQuery(className: "Real Estate") field22.whereKey("field 22", contains: search) let field23 = PFQuery(className: "Real Estate") field23.whereKey("field 23", contains: search) let field24 = PFQuery(className: "Real Estate") field24.whereKey("field 24", contains: search) let field25 = PFQuery(className: "Real Estate") field25.whereKey("field 25", contains: search) let field26 = PFQuery(className: "Real Estate") field26.whereKey("field 26", contains: search) let field27 = PFQuery(className: "Real Estate") field27.whereKey("field 27", contains: search) let field28 = PFQuery(className: "Real Estate") field28.whereKey("field 28", contains: search) let field29 = PFQuery(className: "Real Estate") field29.whereKey("field 29", contains: search) let field30 = PFQuery(className: "Real Estate") field30.whereKey("field 30", contains: search) let objectId = PFQuery(className: "Real Estate") objectId.whereKey("objectId", contains: search) query = PFQuery.orQuery(withSubqueries: [field1, field2, field3, field4, field5, field6, field7, field8, field9, field10, field11, field12, field13, field14, field15, field16, field17, field18, field19, field20, field21, field22, field23, field24, field25, field26, field27, field28, field29, field30, objectId])
