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 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 usefulrelevant tags like search and 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.
