Is there a way to use libffm(external score) to custom score?

Hello
I want to use libffm open source library for accurate ranking of a search query.
How can I do that?
Is there any good way?

One way I know, when indexing, the result score of libffm to field of every document(index) is saved in advance by Spark and sort by using it custom score or simple sort Api instead of _score(Lucene score)
How is it?

Please advice to me.
Thank you in advance.
