Which field type cannot be added as a searchable field?
A . Text Area
B . Currency
C . Picklist
D . Formula
E . Text

Answer: D

Explanation:

According to the Searchable Fields page, searchable fields are fields on the Product object that can be used as filters or facets for search results on your B2B Commerce site. Searchable fields can help users narrow down their search results and find the products that match their criteria. One of the field types that cannot be added as a searchable field is formula. Formula field type allows users to calculate values based on other fields or expressions as search terms. Formula fields are not supported as searchable fields because they cannot be indexed by the search engine and they may cause performance issues or inconsistent results during search. Therefore, option D is correct. Options A, B, C, and E are false because text area, currency, picklist, and text are field types that can be added as searchable fields. Text area field type allows users to enter any alphanumeric characters as search terms. Currency field type allows users to enter numeric values with decimal places and currency symbols as search terms. Picklist field type allows users to select one value from a predefined list of values as a search term. Text field type allows users to enter any alphanumeric characters as search terms.
