Proper Syntax for adding Filters?

I can't remember what the proper syntax is for adding stuff to Alert Filters.

Right click a mob, or on a mob name in the spawnlist and add a alert. Then edit the alert/filters file you added to. Then you can see the exact syntax. You can also add them from a spawn point or a timer. If a named has been observed at that location it will attempt to identify it so it is what shows in the edit box that pops up. Its pretty easy. You can just add many different ways and can just type in what you want anyways.

How can i add a filter for an EXACT match? i.e. if i put "a giant" in the filter, i would only want stuff that is exactly "a giant" and not "a giant bat" etc...
