[Bug] Multiple keyword search does not seem to work as intended

[Ditzchann]

List used:

According to the user guide, any name containing any of the keywords should be found.
Therefore, we expect to see Alice Lee and Grace Yeo through a query find -n Lee Yeo
However, nothing seems to be displayed.

find -n Yeo and find -n Lee seems to work individually

The user guide also states that the order of the keywords do not matter. Yet find -n Lee Alice also does not seem to query any results.
