[Dock-fans] Flexible vs rigid ligand for docking (using DOCK 4.0)

I have a general question about the relationship between particular parameters
and ligand flexibility in DOCK 4.0.
First, by simply putting a 'yes' to the flexible_ligand parameter (without using
anchor search), will this alone be sufficient to bring about a full conformational
search to the ligand (to all rotatable bonds), or will I need to also input 'yes' to
the torsion_drive parameter as well?
In other words, what does the 'yes' for flexible_ligand do? Does that only entail
a final minimization of the ligand (as long as torsion_minimize is on and
torsion_drive is not on)? Or does that entail a more expansive conformational
For a more expansive conformational search for the ligand, what might you
suggest as the optional set of parameters to do this?
If you can provide some feedback to me regarding these issues, that would
be greatly helpful. Thanks in advance.
