Facet count != Query count

[Darren Govoni]

Hi,
  What could cause a facet query on a field (say 'name') differ in count
from a basic query on the field using the same value?

e.g

name:'Darren'

If there are 10 documents that match this, the facet count should be 10
for 'Darren', and I should get 10 results if I query on the field.

But after loading 2000 documents, I am getting different values for
each.
