Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use the limit command to filter results to 1000.
Why it's wrong here
The limit command is not the standard way to constrain subsearch output size.
- ✓
Use the return command to specify the exact number of results to pass.
Why this is correct
The return command allows you to define the number of results and specific fields to return.
- ✗
Apply the fields command before the subsearch ends.
Why it's wrong here
While fields helps, return is specifically designed to control subsearch result limits.
- ✗
Convert the subsearch into a join command.
Why it's wrong here
Joins are generally less performant than subsearches for simple filtering.
