The idea
AND links different concepts and narrows a search, because every joined term must appear in the retrieved record.
In practice
An intervention term joined to an outcome term, returning only records containing both.
Where people slip
Narrowing discards. Records holding one concept but not the other are removed, and some of them were relevant.
