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 are about 10 of these that are "paid results".I need to
list the first 3 (1-2-3) of the paid results (in their ranking decreasing
order) on the first page (maybe by improving the ranking of the 20 paid results
over the non-paid ones and listing the first 3 of them.) and then listing 9
non-paid results on the page in their ranking decreasing order.
Then, on the second page, I want to list first the next 3 paid results (4-5-6)
and so on.
Kind regards,Christian

Hence the suggestion to group by the paid field - would give you two
lists of the number you ask for.
What I'm trying to say is that the QueryElevationComponent might do it,
but it is also relatively clunky, so a pure search solution might do it.
However, the thing we lack right now is a full take on the requirements,
e.g. how should paid results be sorted, how many paid results do you
show, etc, etc. Without these details we're all guessing.
