Question 1

A machine learning team is using IVF indexes in Oracle Database 23ai to find similar images in a large dataset. During testing, they observe that the search results are often incomplete, missing relevant images. They suspect the issue lies in the number of partitions probed. How should they improve the search accuracy?

A. Re-create the index with a higher EFCONSTRUCTION value

B. Increase the VECTOR_MEMORY_SIZE initialization parameter

C. Add the TARGET_ACCURACY clause to the query with a higher value for the accuracy

D. Change the index type to HNSW for better accuracy
