When you are filtering, as you begin typing you are presented with the option to create a wildcard filter based on the current text. Selecting this option will return all results that match the wildcard expression. You can also create expressions using NOT or AND, or you can select the "None" option to filter for null values in the field.

Filters based on wildcards or expressions (e.g. NOT, AND, "None", etc.) display in dark blue in the filter field. Items that you select directly from the list are displayed in light blue.

Kubernetes filters are contextual, meaning for example that if you are on a specific node page, the pod_name filter only lists pods related to that node. Moreover, if you apply a filter for a specific namespace, then the pod_name filter will list only pods on that node and in that namespace.

Note that Wildcard and Expression filtering works with text or lists but not with numerics, dates or booleans.
