Is my parse tableview searching inefficient (swift

Question

So i have a bunch of fields in my parse server and I have a tableview in my iOS app. For each cell there is a bunch of data like I said before. But the problem is that I want to allow a user to be able to search that data. My question is, if I have lets say 50,000 pfobjects of listings and my parse server and a user is searching this many fields, is it going to be extremely expensive or are searches not that expensive. Keep in mind that everything searched is lowercased so it won't be a problem. Here is my code. I have 31 fields I'm searching text. Is this bad to do. Will it ramp up a lot of bills on my server side if I have hundreds of thousands of users. Heres is my code.

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)
