Actually what I wrote assumes you are passing a Catalog not a ZCatalog.
So you will need to change it for a ZCatalog to:
def partialReindexObject(zcatalog, indexes, uid, object):
catalog = zcatalog._catalog
rid = catalog.uids.get[uid]
for idx_key in indexes:
idx = catalog.indexes[idx_key].__of__(catalog)
idx.index_object(rid, object, None)
Sorry about that.
