What is a necessary step before records created with bulk API become searchable in Salesforce?

For records created with the Bulk API to be searchable in Salesforce, they must be indexed. Indexing is a critical process that allows the Salesforce database to organize and retrieve data efficiently. Without indexing, records may exist in the database but would not be available through search queries, making it difficult for users to find relevant information quickly.

Indexing works by creating a data structure that enables faster search operations. Once records are indexed, they can be quickly accessed and returned in search results, improving overall system performance and user experience.

The other options do not directly relate to the process required for making records searchable. Exporting records, manual approval, or backing them up may be important for data management but do not impact the searchability of the records in Salesforce. These steps operate independently of the indexing process, which specifically addresses how records are organized and accessed in the system.
