I'd like to put much more weight on a) category and b) tags instead of titles and bodies, but not require at least 1 or 2 categories or tags.
As I use category as 3-level hirarchical geo coding (Continent > Country > State), the setting "require more than..." would limit it always to the same country. Hence I'd like not to restrict, but to "over" weight the category (bottom-up), because if I just consider all of the four equally, the weight of the category (and tags) is much too low.
Any hint how to solve this?
Thanks in advance!
