Map that contains the index values (forward index). The keys of the Map are the keys to the ResourceMap and the values are the extracted values. This map is used by the IndexAwareFilters to avoid a conversion and value extraction steps.

Map that contains the index contents (inverse index). The keys of the Map are the return values from the ValueExtractor operating against the values of the resource map, and for each key, the corresponding value stored in the Map is a Set of keys to the resource map.

Specifies whether or not this MapIndex orders the contents of the indexed information.
