A and B

A and B!!!

Option D shouldn't be a correct one. How come Find in "ALL FIELDS" can make a faster search?

Option A (Use searches against single Objects for greater speed and accuracy) is not accurate. SOSL is designed to search across multiple objects simultaneously.

Option C (Use SOSL option to ignore custom indexes as search fields are pre-indexed) is not a correct statement. SOSL does leverage custom indexes, and there isn’t an explicit option to ignore them.

When using SOSL (Salesforce Object Search Language) for searching in Salesforce, the following two best practices should be followed:

A. Use searches against single Objects for greater speed and accuracy.
Explanation: Performing searches on a single object rather than across multiple objects can significantly improve search performance and result accuracy. This minimizes the scope of the search, making it faster and more efficient, and reduces the chances of irrelevant results.
B. Keep searches specific and avoid wildcards where possible.
Explanation: Wildcards can broaden the search results and lead to longer processing times. Keeping searches specific allows for more targeted results and faster execution. This helps in returning relevant records without unnecessary delays associated with processing broader searches.
Why the Other Options Are Less Suitable:
C. Use SOSL option to ignore custom indexes as search fields are pre-indexed.

Explanation: This statement is misleading. SOSL uses pre-indexed fields for searches, but it does not have an option to ignore custom indexes explicitly. Custom indexes can actually improve search performance, so it's typically beneficial to utilize them rather than ignore them.
D. Use Find in "ALL FIELDS" for faster searches.

Explanation: Searching in "ALL FIELDS" may return a broader set of results, which can increase processing time and reduce the relevance of the results. It’s generally better to specify the fields to search against to maintain accuracy and performance.
Conclusion:
The best practices for using SOSL effectively are A (Use searches against single Objects for greater speed and accuracy) and B (Keep searches specific and avoid wildcards where possible). Following these practices will help ensure efficient and relevant search results in Salesforce....
