I've seen a similar requirement to this recently.
Basically, a sorting requirement that is close to impossible to
implement as a scoring/boosting formula, because the *position* of the
result features in the score, and that's not something I believe can be
done right now.
The way we solved the
Would result grouping work here? If the group key was "paid", then
you'd get two groups back, "paid" an "unpaid". Within each group you'd
have results ordered by rank. This would work for a page or two, but
eventually you'd be in a spot where you'd have to over sample, i.e.
return pages*X in each
Hi Upayavira & Walter & everyone else
About the requirements:1. I need to return no more than 3 paid results on a
page of 12 results2. Paid results should be sorted like this: let's say a user
is searching for: "chocolate almonds cake"Now, lets say that 2000 results match
the query and there
By far the easiest solution is to do two queries from the front end.
One requesting three paid results, and one requesting nine unpaid results.
If all the results are in one collection, use “fq” to select paid/unpaid.
That is going to be fast and there is zero doubt that it will do the right
