The Person Management page search in Oracle HCM Cloud uses the "Update Person Search Keyword" process to index attributes like job. This process updates the keyword record with thelatest effective-dated value(here, "Consultant" as of 01-Feb-2015) as of the process run date, overwriting historical data (e.g., "Recruiter" from 01-Jan-2015). On 01-Mar-2015, searching with "Recruiter" and an effective date of 31-Jan-2015 fails because the index only contains "Consultant," not historical jobs, even though date-effective search is supported.

Option B is false—job keywords are supported. Options C and E (process failures) lack evidence. Option D is incorrect—date-effective searches are supported via ORA_PER_EMPSRCH_ENABLE_DATES. Option F misstates the process—it doesn’t associate effective dates; it overwrites with the latest. Option A correctly explains the behavior per Oracle’ssearch mechanics.
