In Enify - My workspace, click the Tags button. Search for and click on a tag (or use the scroll bar) you know exists in an element, board or folder.

The Tag you selected will be marked (to deselect just click the marked Tag again)...

..and all the element, boards or folders containing the Tag will be shown.

If you select several Tags, the "And/Or" filter comes into play. Here we selected "And" meaning that the both Tags must be present in the items you look for.

Here we selected "Or" meaning that either the first Tag or the second Tag must be present in the items you look for.

Use Tags to look for elements, boards and folders that are marked with tags.
