It appears that repeating characters are getting collapsed/ignored. Search on harrrrrr and you'll get the same results.

OK. That sort covers one aspect and I can see that searching for harrrrr gives me the same results as harr. Collapsing/ignoring repeated characters may explain why when searching for harr I get the name Richard in the results.  It does not explain the results when I search for jone which has no repeating characters.  In this case, I see numerous members with the surname Jones but also several that do not contain those consecutive letters in either name nor email address.
