Excellent, thanks. I've just tested it and it seems to work as expect.

I wasn't aware you could do that, so I'll add that in to our debug
output.

Got it. Delve shows the terms prefixed correctly.

Absolutely. The issue with the Term Prefix page is that it doesn't show
you a full example, specifically: here's how you index it and here's how
you search it. In the last example, what would be good would be to have
a separated out example showing how to JUST search the title, rather
than title OR something else. 

Would you like to write you a short segment?
