As a quick win, we just implemented this via string hacking (here)
Now that this functionality is stable and works, we should make it a bit more idiomatic
We originally used string hacking over FtColumn because we didn't (and still don't) need a FtColumn::Object of serialized FtColumns, because we're merely saving references (i.e., IDs) of items, and not the items themselves
However, we should replace the string hacking with the use of FtColumn
