[KinoSearch] Schema change in 0.20

[Henka]

Hello Marvin,

>From the docs for 0.20 I read:

"Note: It's crucial that the Schema that you use at search-time be
identical to the one used at index time. KinoSearch will get very confused
if you change up the list of fields, for example."

In 0.15 and below, I could add or remove special fields during indexing,
and things would still (seemingly) work.

Do I understand you correctly from the docs that this is no longer
recommended in 0.20, or does the above note specifically refer to the
ORDER of special fields (meaning one can still add/remove at the bottom of
the list)?

Thanks
Henry
