Categories-Tags Search

If my post over the MU has category and tags, does the Global Search Plugin find them?

For example I have posts over the MU in category “NEWS” and all of them has the TAG “Cool”

If I insert “NEWS” or “Cool” in the Global Search plugin, the results bring me the 3 posts?

I tried to do it without results.

The global search plugin, search only in Title and the Body of the post?
