Fred,

I've corrected 10.1 : it now says:

1. ORDER BY: put the solutions in order
2. Projection
3. DISTINCT: ensure solutions in the sequence are unique.
4. LIMIT: restrict the number of solutions processed for query results
5. OFFSET: control where the solutions processed start from in the overall 
sequence of solutions.

Please let us know if this responds to your comment,
