# ParametricMaxPairsPerDocument

The maximum amount of memory that can be used for a single document to store information for the specific restriction case. This parameter has an effect only if you set ParametricRefinement to `True`.

Micro Focus recommends that you set `ParametricMaxPairsPerDocument` to `0`, which reduces the memory required for parametric refinement.

You must set `ParametricMaxPairsPerDocument` to a non-zero value if you want to use the GetTagValues action with the Restriction parameter.
