Querying VAST Catalog from the VAST Web UI

From the Column name dropdown, select the column based on which you want to search.

From the Select operator dropdown, select from the available operators, which are suited to the data type stored in the selected column. Then provide any relevant further criteria.

For example, for the column group_owner_name, you can select either is exactly to search for a given group, and then enter a group name into a provided field, or is null and then select True or False to search for all entries that have a group owner name or for entries that do not have group owner name.

If you want to extend the query by adding OR criteria for the same column (to return results with either the above condition or another condition based on the same column), click OR, select another operator for the column and complete any relevant further criteria. Repeat as needed for additional OR criteria.

When you are done defining the condition, click Add .

The condition is added to a list of conditions.

If you want to limit the query by defining AND conditions so that the query will return only results that match the condition already listed AND further conditions, repeat the above steps to add further conditions to the list.
