Categories - other names

Categories - other names

In the categories module under an individual category item there is an option to add an "other name". The manual indicates that this is the preferred way to add ambiguous terms. So for example the category "nursing home" could have "hostel" as an 'other name'.

When I add "hostel" to the category of notes or references should these then be returned in a category search for "nursing home"? ie I should get all the records with the category "nursing home" plus all the records with the 'other name' designation of "hostel"?

The reason I am asking is that this does not seem to happen, and yet this seems to be the logic behind using 'other names'.
