Searching for tags to tag a question sometimes requires a certain amount of trial and error, but in this case finding the right tags for your question was not difficult. [tag:tag] was an obvious tag to start with because of the high probability that someone already asked a question at Ask Ubuntu Meta related to this tag. Surely the volunteers who help to create new tags wouldn't be likely to have not created other useful tags like [tag:search] and [tag:profile-page] either. 

By the way you can hover the mouse over any tag including the tags in this answer to show information about the tag.
