DocSlice andNotSize

[Candide Kemmler]

Hi,

I have a simple question rel the DocSlice class. I'm trying to use the  
(very handy) set operations on DocSlices and I'm rather confused by  
the way it behaves.

I have 2 DocSlices, atlDocs which, by looking at the debugger, holds a  
"docs" array of ints of size 1; the second DocSlice is btlDocs, with a  
"docs" array of ints of size 67. I know that atlDocs is a subset of  
btlDocs, so the doing btlDocs.andNotSize(atlDocs) should really return  
66.

But it's returning 10.

Any idea what I'm understanding wrong here?

Thanks in advance.
