Agregate Similarity Objects

It would be super if you could agregate similarity object scores (preferably even weighted). For example

- Use the title score, weighted 0.8
- Add terms score, weighted 0.5
- Add Voting score, weighted 0.2

I think, in principle, the user is not really interested how you got the similarity, only if its relevant. Using agregated scores, the results become much more fuzzy, and with some proper trial-and-error can be much more interesting.
