+`"ComplexCoarseSolve" [true]` : When set to `true`, the coarse-level solver uses the true
+complex-valued system matrix. When set to `false`, the real-valued approximation is used.

 `"PCSide" ["Default"]` :  Side for preconditioning. Not all options are available for all
 iterative solver choices, and the default choice depends on the iterative solver used.
