Application Search is a new feature in Oracle APEX 22 that allows you to search for and navigate to various components within your APEX application. You can use the Application Search to quickly find pages, regions, items, buttons, and other components within your application without having to navigate through menus and hierarchies.

Here’s a step-by-step tutorial on how to use the Application Search feature in Oracle APEX 22:

1. Launch Oracle APEX and open the application you want to search in.
2. Click the Application Search button in the top right corner of the APEX interface. Alternatively, you can use the keyboard shortcut Ctrl+Shift+F to open the Application Search dialog.
3. In the Application Search dialog, you can start typing the name of the component you want to find. As you type, the search results will appear in real-time, and the list of results will update based on your search query.
4. The search results will show the name and type of the components, as well as the location where they are defined in your application. You can click on any search result to navigate to the component within your application.
5. You can also use the filter options in the Application Search dialog to refine your search results based on various criteria such as component type, modification date, author, and more.
6. In addition to searching for components, you can also use the Application Search feature to launch various APEX development tools and utilities, such as the Page Designer, Component View, and more. Simply type the name of the tool or utility you want to launch in the search bar, and click on the search result to open the tool.
7. If you want to customize the Application Search settings or keyboard shortcuts, you can do so by clicking on the gear icon in the top right corner of the Application Search dialog and selecting Preferences.

In-depth Usage: The Application Search feature in Oracle APEX 22 provides several advanced capabilities that allow you to perform more complex searches and streamline your development workflow. Here are some examples of how you can use the Application Search feature in more depth:

1. Search for components with specific attributes – You can use the Advanced Search feature in the Application Search dialog to search for components that have specific attributes such as a specific CSS class, a certain template, or a custom JavaScript code. Simply click on the Advanced Search button in the search bar and enter your search criteria.
2. Search for components by modification date – You can use the Date Range filter in the Application Search dialog to search for components that were modified within a specific date range. This can be useful when you need to review recent changes made to your application.
3. Search for components across multiple applications – If you have multiple APEX applications in your workspace, you can use the All Applications filter in the Application Search dialog to search for components across all your applications. This can save you time and effort when working on large projects with multiple applications.
4. Search for components using regular expressions – If you need to perform more complex searches, you can use regular expressions in the search bar to search for components based on specific patterns or sequences. For example, you can use regular expressions to search for all components that have a certain prefix or suffix in their name.

In summary, the Application Search feature in Oracle APEX 22 provides a powerful and intuitive way to search for and navigate to components within your APEX application. With its real-time search results, advanced filtering options, and customizable settings, the Application Search feature can help you streamline your development workflow and improve your productivity.
