Hey all.
Pardon my ignorance. :-)
I've been trying to figure out whether null values are indexed or not from
the documentation. I was under the impression, that null values are not
stored in the index. Occassionally, though, I then see a suggestion such
as the above, that seems to indicate to me that null values *are* stored
in the index, allowing for the 'exclude null values' to have effect?
Which is it? :-)
Thanks,
mark
