I think it depends on how you interpret the results. The top answer (for "cahors") is a paid for link for holiday cottages in France (try it). The right hand side is full of paid for links to holidays in France, and the bottom of the page contains related searches to holidays in France.
I think the OP is right in that the Google search does give the results as stated, but then those results need to be understood in the context of how Google presents search results; the actual results do only show this site (and yes, I do understand the difference between the browser search box - mine is removed - and the search box for the Forum).
