First stab at document scoring. This is made harder by the fact that score() evaluates expressions that merely contribute to scoring. So match predicates return true/false, not a score, so we have a few options:
Specify a whole "parallel" expression specification that says "if used in scoring mode", the algorithm is: ..."
Re-specify all predicate operators/functions as returning a PredicateResult { result, score } or a tuple (result, score) or similar.
Handwave it away and say that score() evaluates the predicates and assigns a score based on whether the , but not exactly how. This is what I've done so far.
