The Global Search in Oracle HCM Cloud relies on the "Update Person Search Keyword" process, which maintains a keyword index for person records. This process updates the index with the latest effective-dated attributes (e.g., job) as of the process run date, not historical data tied to specific effective dates. In this case, the employee’s job changed from "Recruiter" (effective 01-Jan-2023) to "Consultant" (effective 01-Feb-2023). By 01-Mar-2023, when the HR specialist searches, the keyword index reflects the latest job ("Consultant") because the process overwrites prior values with the most recent effective-dated record. Thus, searching for "Recruiter" with an effective date of 31-Jan-2023 fails because the historical job isn’t preserved in the index—only "Consultant" is searchable.

Option A is incorrect because Job attributes are supported in searches. Options B and D (process failures) lack evidence and don’t explain the behavior. Option C is misleading—effective dates aren’t associated in the index; they’re overwritten. Option E is wrong because date-effective searches are supported, but the index limits results to current data. Option F correctly identifies that the latest job ("Consultant") replaced "Recruiter" in the keyword record.
