You can create an index on a snapshot or a dataset when you publish these objects to Toad Intelligence Central. A single index is created on each of the columns you select. Any indexing on the remote objects is not inherited by the dataset.
Note: When you select multiple columns to index, a single index is created on each column. A composite index is not created.
