Suggestions based on facet are too lengthy

I’m trying to create query suggestions index from facet.

My facet values (just couple of them):
young slim woman standing and turning her head
young slim woman standing and holding sunglasses
old woman with closed eyes, smiling and touching hair
Man proposing getting marriage to happy woman

And 3K+ more records like this. I want my suggestions look like
young slim woman
old woman smiling

But what I have is 185 suggestions like
young woman standing and holding the present in the studio indoor holiday christmas
with 1-3 matches.

Minimum hits = 2.
If I increase minimum hits to 3 it creates 19 suggestions but all very lengthy

Are there any ways to generate shorter suggestions?
