This is a specialized ZCatalog index type which does not actually store False values in its forward index and thus reduces the persistent footprint of the index.
Queries for True values are done with a normal intersection against the forward index.
If experimental.catalogqueryplan is used queries for False values are done via the difference of the passed in result set and the forward index. If no result set is passed in, the difference of the forward index and the unindex is used.
