Hello CFifield78,
Welcome to the Apple Support Communities!
I understand that you are curious if your Maps searches sync between your iOS devices. Your searches do not sync across devices automatically, but you can save locations or address in your Favorites that will be shared across your devices. The attached iOS 8 User Guide explains this process (page 98).

To share the location, add the location to your Favorites, or use another app you install, tap .
This process is also mentioned on the following webpage. I would suggest reading over this site as well for use as a reference.
Apple - iOS 8 - Maps
When you hear about a great new spot — like a restored drive-in movie theater or a restaurant-slash-boutique — save it as a bookmark in Maps. And spare your future self the need to remember the names and addresses of those places all over again. iCloud stores the locations you’ve bookmarked, so they’re accessible on your Mac, iPad, iPhone, or iPod touch.3 iCloud also lets you send a map from your Mac running OS X Mavericks straight to your iPhone. When you’re signed in to iCloud on both devices, your phone shows up in the Share menu on your Mac. So you can plan your trip at your desk and get turn-by-turn voice navigation on the go.
Have a great day,
Joe
