how to have notes included in search

One of the main reasons that I wanted to have notes is to make certain emails more searchable (not everyone is helpful in the way they fill our the "Subject" line).  I wanted to be able to add my own quick note on the subject of the e-mail so I could more easily find it later on. However, I see that when I do a general search for an e-mail that I wrote a note in - it doesn't show up in the search results.  Can this be fixed? Could this be something for a future update of MNP?  Thanks!

I am also longing for a possibility to search trough notes. Any hints or other addons?
