I'd like to increase the weighting of one metadata class: "keyword". So that query matches are more likely to appear at the top of the result list.
It looks like this is the way to do it, but I'm not 100% sure how to use it.
https://docs.funnelback.com/15.20/customise/metadata-customisation/controlling-metadata-field-weighting.html
By default link text, clicked queries and titles are included (-sco=2[k,K,t]).
It appears that if I want to keep the default weighting, I should use these values and append my own rules. I only need to add a wmeta value for the added metadata class. Is this correct? Eg to double the weighting of keywords:
-sco=2[k,K,t,keyword] -wmeta.keyword=2.0
