Walter -
How about this, for the latter part of your request:
/handler?features=a,b,c
with &sort=sum(${features}) desc
That ought to do the trick. At first I thought the #foreach nature of the
list of features was prohibitive, but since you’re literally plugging in the
exact string value and it’s used as a comma-separated list then this should
work.
But with the just a list of subject ID’s I think you’re in custom development
now (or a JavaScript stage in a Fusion query pipeline ;) in building a
SearchComponent that takes a `features` parameter and builds the sort param as
needed from that.
