Which three field types can be added as Searchable fields?
A . Picklist
B . Auto Number
C . Formula
D . Text Area
E . Currency

Answer: ADE

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. Three of the field types that an admin can set as searchable fields are picklist, text area, and currency. Picklist field type allows users to select one value from a predefined list of values as a search term. 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. Therefore, options A, D, and E are correct. Options B and C are false because auto number and formula are not field types that an admin can set as searchable fields. Auto number field type allows users to generate unique numeric values for each record as search terms. Formula field type allows users to calculate values based on other fields or expressions as search terms.
