newbie question: can one search by 'Rating' or "Favourites'?

You can add any tag name to your files (depending on what your tagging program will allow) and configure the tag name for indexing/browsing by adding it to the MinimServer indexTags property.

Browsing is normally by tag name and value (for example, Rating>5) but you can combine the two steps by adding an automatic selection value to the indexTags name. For example, to browse by Favourites, you could set all your Favourites tags to the value 1 and put Favourites=1 in indexTags.
