Search can't find a tagged item

Using the info button I tagged an item Personal. When I search on this it doesn’t find the item. Any idea why.

PS Just curious - is this considered metadata.

For the purpose of searching in DEVONthink, tags are not considered to be metadata. You can search for tags using the Tags view or enter the tag criteria using the ‘Advanced’ button in the Sidebar of the search window. BTW, the manual includes info on metadata fields that may be helpful in creating your searches.
