Expert: Describes the score computation for document and query.
solver.explanations.Explanation
An explanation is the combination of two sets: a set of deduction and a set of propagators. The deductions are stored in a list, and the uniqueness of elements is ensured during the add operation. This allows fast iteration over elements. The propagators are stored in the same way.
