Solution Pool

I am using the solution pool feature of Gurobi. I set PoolSearchMode = 2.

1. My formulation is an MILP. In my problem, the integer variables are more important than the continuous variables, and I only care about the integer ones. Will Gurobi only deem two solutions distinct when their projections onto the integer space are different? In fact, in my problem, there exists infinite number of optimal solutions when the integer ones are fixed, so I really want to ignore the trivial part.
2. If I set PoolSolutions to a sufficiently large value and PoolGap to 0, will Gurobi enumerate all distinct optimal solutions?
