**Description:**
Examples in the "Select by similarity" section were not really
highlighting capabilities of similarity search.
E.g. "# Input is a measurement, so should select the tall/short example"
was still outputting the "mood" example.
I tweaked the inputs a bit and fixed the examples (checking that those
are indeed what the search outputs).
