How to call a stored JavaScript function to add a field to objects returned by a query using linq and c# driver - mongodb

Question

I have this query:
var professionalProfilesQuery =
(from profileCollection in _mongoContext.Database.GetCollection<Profile>("profiles").AsQueryable()
join userCollection in _mongoContext.Database.GetCollection<User>("users").AsQueryable()
on profileCollection.UserId equals userCollection.Id.Value
into users
orderby profileCollection.Name
select new ProfessionalProfile
{
Id = profileCollection.Id,
Name = profileCollection.Name,
UserId = profileCollection.UserId,
IsConfirmed = users.First().IsConfirmed,
})
.Where(p => p.IsConfirmed);
And then I have a stored javascript function in DB that calculates a "Score" for each ProfessionalProfile according to data in several collections (I need to sort results later according to that score). Something like:
function candidateScore(objectWithDataToCalculateScore, professionalProfile) {
var score = 0;
//Calculate score here
return score;
}
Is it possible to add a field to data returned by the query with the calculated score? How can I call the stored javascript function to do so? I'd like to do something like:
var professionalProfilesQuery =
(from profileCollection in _mongoContext.Database.GetCollection<Profile>("profiles").AsQueryable()
join userCollection in _mongoContext.Database.GetCollection<User>("users").AsQueryable()
on profileCollection.UserId equals userCollection.Id.Value
into users
orderby profileCollection.Name
select new ProfessionalProfile
{
Id = profileCollection.Id,
Name = profileCollection.Name,
UserId = profileCollection.UserId,
IsConfirmed = users.First().IsConfirmed,
Score = ***CallToCandidateScoreFunctionHere...***
})
.Where(p => p.IsConfirmed);
If that's not possible or it's not a good way to do it, would you suggest another approach instead of stored javascript function?
Thanks.
EDIT: After reading comments from Neil Lunn, I'll explain better the calculation I need.
This is an example of the class that models the collection that would be the first parameter in the previous candidateScore javascript function:
public class ProfessionalProfileRequirements
{
[BsonId]
[BsonRepresentation(BsonType.String)]
public Guid Id { get; set; }
public string Role { get; set; }
public string Province { get; set; }
public IEnumerable<string> LanguagesRequired { get; set; }
public IEnumerable<string> SkillsRequired { get; set; }
}
And this the javascript function again with some of the calculations (it's quite complex, so I simplified it. I hope it's enough to show what I need):
function candidateScore(professionalProfileRequirements, professionalProfile) {
var score = 0;
if (professionalProfileRequirements.Province === professionalProfile.Province) {
score += 1000;
}
if (professionalProfileRequirements.Role && professionalProfile.Roles && professionalProfile.ExperienceLevel){
if (professionalProfile.Roles.includes(professionalProfileRequirements.Role)) {
switch (professionalProfile.ExperienceLevel) {
case 'ExperienceLevel_NoExperience':
score += 1;
break;
case 'ExperienceLevel_LessThanOneYear':
score += 2;
break;
case 'ExperienceLevel_BetweenOneAndThreeYears':
score += 4;
break;
case 'ExperienceLevel_BetweenThreeAndFiveYears':
score += 6;
break;
case 'ExperienceLevel_MoreThan5Years':
score += 10;
break;
}
}
}
return score;
}
I don't know how I can do that kind of calculation using "aggregate". Any help or any other approach I could follow would be appreciated.
