You can create search page that allow users to enter search criteria into input fields for known attributes of an object.The search criteria can be entered via input text fields or selected from a list of values in a popup list picker or dropdown list box. The entered criteria is constructed into a query to be executed. Named bind variables can be used to supply attribute values during runtime for the query. The results of the query can be displayed as a table, a form, or another UI component as per need.
Search page are based either on view criteria defined in view objects or on implicit view criteria defined by JDeveloper. Search pages are region-based components that are reusable and personalizable. They encapsulate and automate many of the actions and iterator management operations required to perform a query.
You can create several search forms on the same page without any need to change.
