如果您为所有文本框添加了必填字段，首先，当您单击按钮时，它将检查页面是否有效。您需要输入所有必填字段并单击搜索按钮，然后才能获得搜索结果。根据您的要求，iteam_id字段是唯一需要的文本框，其他字段是可选的。因此，使用验证器根据需要制作该文本框并删除所有其他文本框验证器

If you put required fields for all your text boxes,first it will check page is valid when you click on button. you need to enter all the required fields and click on search button, then only you get the search results. As per your requirement iteam_id field is the only text box which is required, others are optional. So make that text box as required by using validator and remove all other textbox validators
