Answer:

The correct answer is C. Sometimes.

Explanation:

A database index is a structure that aims to speed up selections and selective operations on a database. An index reduces the number of comparisons required to find one or more database records. This avoids having to perform a so-called full table scan, whereby all records in the table have to be run through sequentially.

Therefore, if the search does not focus correctly on the necessary data, this search will not always determine the index of the goal. Therefore, the user must correctly handle the search keywords to collaborate with the system.
