Perhapse this is a XY problem. First of all I don't have a site which I want to boost. All docs are equal.
Secondly I will explain what I have. I have 100 docs indexed. I do a query which returns 10 found docs. 8 of them from one site and 2 from other different sites. I dont like order. Technically scores are good. I understand why these 8 docs go first - because they havebetter matching. But i dont like it. I want that articles from smaller collections would somehow compete with other docs. For other queries situation can change and another site can produce more results. In that case i would lower that site. I've had a deep thought and think can try grouping. More insites on my problem. These 8 docs have similar text which matches query and thats why they all get similar and relatively high score. For example docs have text: 1. Red apple felt from tree 2 blue apple felt from tree 3 green apple felt from tree ... 8 orange pineapple felt from tree 9 a boy felt suddenly ill. A tree was green. 10 two pices felt apart and newer collapse. Family tree was reach. I query "felt tree". Docs 1-8 from one site. I would like to make the score of docs 9 and 10 higher. Grouping can help but maybe there are othe solutions.
