"ZCatalog" is essentially a configuration device for the "Catalog".
Searching, indexing, adding columns and indexes essentially
work for "Catalog" as they do for "ZCatalog".

You are using "Catalog" in an "unsupported" way.
Therefore, you must expect to look at its (and that of ZCatalog)
code from time to time to find out some relevant details.
