Default Search Settings on Ancestry.com for NY Federal Non-Population Censuses

I am confused.

I searched for the last name of Drolet in the non-population 1850-1880 census schedules at Ancestry.com. The help box tells me that "default" name settings will get exactly what I typed, Soundex matches, or "similar meaning or spelling to the one you typed."

There were no matches as can be seen in the bottom screen.

Yet when I change the search options on the last name to "restrict to exact--soundex" I get matches with the spelling of the last name as Draulette. Draulette is the soundex equivalent of Drolet (what I typed in) and it should meet the definition of "similar meaning or spelling to the one you typed."

Am I not understanding the default settings?

I do NOT like the default setting of "similar meaning of spelling to the one you typed." That doesn't really mean much to me and with that I don't know how to tweak my search.
