The AppSearch table contains properties needed to search for a file having a particular file signature.
The AppSearch table can also be used to set a property to the existing value of a registry or a .INI file entry. AppSearch action uses file signatures to search for existing version of this information to determine where upgrades are to be installed.

Appsearch
AppSearch Table used along with 4 different tables. I.e. DIrLocator, RegLocator, IniLocator, CompLocator. Hence File , Directory, Ini file , Registry as well as component can be searched on system. One can use Launch condition and Appsearch with complementing each other and with proper sequencing.
I am not sure how App-search actions are used to determine upgrade. may be more user defined custom Actions are required.
There are Windows installer custom action Like "FindRelatedProduct", "RemoveExistingProduct",responsible for major upgrade.

upgrade...
One can only assume he is referring to setting component conditions / feature conditions and such which could determine if files within a component will be deployed depending on REINSTALLMODE or some other very closely related items...
I second...
Yeah. I do second this thought. He may be meaning system search which is genrally used for pre-requisite checks.
