解析查询仅返回第一个和最后一个查询

Question

我正在使用多个元素在Parse中创建一个查询。问题是我的查询只返回第一个和最后一个结果，我不知道为什么。任何有关此问题的见解或更好的查询多个对象的方法都将受到赞赏。

var GroupDetailObject = Parse.Object.extend("Group_Detail");
var query = new Parse.Query(GroupDetailObject);
var tempQuery = new Parse.Query(GroupDetailObject);

query.equalTo("groupId", {
    __type: "Pointer",
    className: "Groups",
    objectId: groups[0].objectId
});

for (ss = 1; ss < groups.length; ss++) {
    tempQuery.equalTo("groupId", {
        __type: "Pointer",
        className: "Groups",
        objectId: groups[ss].objectId
    });
    query = Parse.Query.or(query, tempQuery);
}

query.find({

public class Product {
private String productName;

public String getProductName() {
    if (productName != null || !productName.equals("")){
        return productName;
    }else {
        return "Product Name Not found";
    }
}
public void setProductName(String productName) {
    String productName2 = productName;
    if (productName != null || !productName2.equals("")){
        this.productName = productName;
    }else {
        this.productName = "Product Name Not found";
    }
 }
}
