Hello again, Thanks for your immediate response. As i understand, the only way to boost the values is on query side, right? The Problem is, that i need to boost field values. Okay, some more details: I need it for a library. The string in the field i'm working with is something like "Title author year_of_publication some_catchwords" and so on. It's like on big String. This field is called "Free-Text" so the query can something like "author AND title". And that's the point, the order of the search terms is arbitrary so i don't know what i do boost in the field. If i want to boost the title i need to boost the specific value in the Free-Text field. If I'm wrong and i can handle this problem with using payload, could someone please explain it cause i don't understand how to use payload on index side.
