You'd have thought so, yes, and that's how we started.
However, when I run the 'check url' tool on that /courses directory, I get an 'all ok' message - 117 live URLs found.
But when I change the settings of the collection to start at /courses and include only /courses, the update process fails because:
Swap Views: This data set has only 0.8% (1/123) as many docs as the last one.
...which means, I guess, that the indexer has only found a single URL in that directory - and that's what happens if we start with these settings.
There's no change in the 'exclude' settings, by the way.
A bit flummoxed....
