Can I use OS X Notes app from 10.9+ on 10.8 I recently read a question which explained that the ability to search Notes was introduced in OSX 10.9 and above.  Earlier versions will show you which note a search query exists in but will not search the note itself.

My question is:

Can I use a newer version of notes from 10.9 or 10.10 on OS X 10.8?  I'd like this extended functionality but do not want to upgrade my entire OS just for this one feature.
No, it is not possible to use versions of applications designed for (or included with) a later version of OS X on a prior version.
