In NetSuite's Saved Searches, encrypted fields such as Credit Card Numbers can indeed be included in search criteria, but their use is limited by a specific set of operators due to the sensitive nature of the data they contain. This limitation is designed to protect the confidentiality and integrity of encrypted information while still allowing for the fields to be useful in constructing meaningful search queries. For example, operators that do not require the decryption of the field's content to function (such as "is empty" or "is not empty") can be used. This approach balances the need for security with the flexibility to include encrypted fields in saved searches for administrative or auditing purposes.References: NetSuite's official documentation and Help Center articles on creating and managing saved searches, with a focus on the special considerations for including encrypted fields.
