Ah - the one bit of LIA I haven't read yet is the case studies
section!
Many thanks, I'll check it out. Sorting by multiple fields isn't quite
what I want - that sorts entirely by field A, then uses field B for
records where A is identical, correct?
Correct.
What I really want to do is sort by "A * (1-(B/700))", where A is the
score, and B is the age (in days) of the document. IE - the score is
basically "scaled down" with date.
Maybe the TSS case study will help, though they rebuild their index
nightly and can adjust the boost based on the current day.
I've not come across a really clean way to do this sort of age-based
boosting other than how TSS does it.
