Which of the following is NOT a formula type used in saved searches?

In the context of NetSuite saved searches, there are specific formula types that can be utilized to manipulate and analyze data effectively. The types of formulas commonly used include "Formula(currency)", which allows users to perform calculations and return results in monetary values; "Formula(date/time)", used for operations involving dates and times; and "Formula(text)", which handles string manipulation or text-based results.

However, "Formula(array)" is not a recognized formula type within the framework of saved searches. Arrays are data structures that cannot be directly manipulated or returned as part of a saved search in NetSuite, as saved searches primarily return scalar values like text, currencies, and date/time. Therefore, the absence of "Formula(array)" among the available formula types is why it is the correct answer to the question. Understanding the available formula types is crucial for effectively creating and utilizing saved searches in NetSuite.
