You can create a search filter from scratch. When you create a search filter, it exists only for you. However, with the correct global permission, you can share the filter with other users. By default, no search filter is applied.
Tip If no results are shown when you select a saved filter, it may be because the filter applies to a different search tab. For example, if you have the Data Marketplace tab selected and see no results, try clicking the All results tab.
