Hi Claire,
Before you can use the autosuggest feature, you have to create an autosuggest dictionary which is only possible with 10,000 translation units (i.e. segments) in your TM. Not counting the 10,000-TU requirement, the same applies to terms: for your Fontainebleau to be recognized, you need to create a termbase first.
I am not sure how exactly your concordance search 'is just not working'. Whether you invoke it by selecting a word in source column and then pressing F3, or whether you expect it to pop up but it doesn't?

Hi Claire,

Sorry to hear about your frustration with AutoSuggest. It sounds like you want to see two particular AutoSuggest features working: upLift and term recognition.

For term recognition, you do need to create a termbase and feed it manually. That would help with your Fontainebleau example. Here's a link to a video that explains the basics of getting started with a termbase: 

For upLift to work, your TM needs some previous preparation (upgrading) before fragments start being offered. If your TM was created in Studio 2017, then fragment matching should kick in as soon as you pass the 1000 translation unit mark. If it's an older TM, make sure to select Upgrade for your TM, and it will be prepared for fragment matching. Then, there's one more thing you need to do. Go to Project Settings, find your TM, go to Search, and make sure you enable fragment matching for TU Fragments (disabled by default). If you'd like to see even individual words come up in AutoSuggest, you can lower those numbers.

Regarding Concordance, I'm a bit puzzled, the only reason Concordance wouldn't work is if the Concordance checkbox in the TM is unchecked. Are all the right boxes checked in your TM under Project Settings? Or do you mean you're not getting Concordance suggestions in AutoSuggest?
