Labelling Word Files

[Hoaryhairs]

I have a large number of word files which are basically notes for speeches. I want to be able to tag them with criteria such as where that speech was made, when it was made, some form of rating, where I might use it in the future, etc. I also need that information to be searchable. Is this possible with word files? If so could you point in the direction of where I can find out how? I'm using Office 2010.
