How can I exclude fields from the Global Search tool?

Is it possible to exclude certain fields from the Global Search tool? Typically key fields and system fields should not be searchable using Global Search.
 

To exclude fields in the search tool, use the Search statement in the script.

Example

Search Exclude *ID;

Exclude all fields ending with ID from searches in the search tool.

Several Search statements can be used to refine selection of fields to include in the search tool. The statements are evaluated from top to bottom.
 

Example

Search Include *;	Include all fields in searches in the search tool.
Search Exclude *ID;	Exclude all fields ending with ID from searches in the search tool.
Search Include ProductID;	Include the field ProductID in searches in the search tool.

The combined result of these three statements, in this sequence, is that all fields ending with ID except ProductID are excluded from searches in the search tool.
