Priority/Rank in Search Result

We have some fields we want to rank differently in the search result. For example we want the product name and brand to have a higher score than the product description.
Do I just set boost to all of theese field like 1-10 or how do I score theese different fields?

This is our priority for example:

  1. Manufacturer Articlenumber
  2. Name
  3. Alternative Search Words
  4. Brand
  5. Category
  6. Short Description
  7. Long Description

Litium version: 6.2.2-patch-1810041453

You need to build the search query and put all of this fields in an OptionalTagClause with different boost, see https://docs.litium.com/documentation/architecture/search/boosting-search-results how to work with boost’s.
