I think the big question here is, how are you trying to *use* the contents
of this hypothetical third field? If it's for display on a template, for
instance, you could do something like...
<$list filter={{!!bucket}}>
<<currentTiddler>>-{{!!primarytopic}}
</$list>
...which would display each bucket along with the primary topic. You could
use a second $list if there can also be multiple primary topics (but
presumably the name suggests there can't be).
If you're trying to search based on the bucket and primary topic, you
probably shouldn't be doing this in the first place, as you can easily
apply criteria to multiple fields using a filter anyway.
I can't think of a situation where one of these methods wouldn't work, but
there might well be one. But without further information on your use case,
it's going to be hard to figure out the best way to do it.
