Ability to specify facet weight, so we can allow search engines to index facet pages

Hello,

history: #1370342: Implement a setting to add "rel=nofollow" to facet links

Would like to establish facet weight, so rel nofollow can be removed or sculpted. Example:

Facet 1 - color - weight 1

• blue
• black

Facet 2 - animal - weight 2

• lion
• zebra

So, if user browses to
blue -> lion

all good

but, if user browses to
lion -> blue

facets are rearranged according to weight, and user is redirected to

blue -> lion

The result is the same, and the search engines wont penalise for duplicate results, with slight name variation.

Another option would be to remove nofollow if facet level matches weight. This way, a redirection can be avoided. For example
Facet 1 - color - weight 1

• blue
• black

Facet 2 - animal - weight 2

• lion
• zebra

Facet 3 - height - weight 3

• tall
• short

So, if a search engine bot goes to

lion everything is nofollowed

if a search engine bot goes to
blue
every animal facet is nofollowed, and search engine can continue to

blue -> lion

at this level, every height facet is nofollowed etc.
