So now I'm wondering what additional criteria have been folded in that can trigger multiple results.
From my observations its specialisms
A site that specialises in copper widgets and a query for the same, will have links to gold copper widgets, bronze copper widgets, green copper widgets.
Actually its a bit deeper into the lontail query of "widgets" than the above implies.
