Global Search Overview
Global search allows you to search any page, record, or field anywhere in your account data by entering keywords into a search field. You can find the search field at the top of any NetSuite page. For more information, see How to Use Global Search.

You can adjust the global search preferences under the Analytics subtab at Home > Set Preferences. For more information, see Analytics Personal Preferences.
Menu Search
The Menu Search feature is an enhancement to the global search. When you enter keywords in the global search field, search results include all hierarchy levels within the navigation menus including the Help Center, Create New button, Feedback, and others. The enhanced results appear under a Menu Results heading.

The Menu Search feature is enabled by default. To disable the menu search, go to Home > Set Preferences. On the Analytics subtab, clear the Page Search box.
