Design range (sensitivity) bar intuitively
I am building a website that includes a page that has a search input and a sensitivity bar near him that allows the users to control over the amount of results returned and their accuracy.
The site design look like this:
The sensitivity bar looks like this:
When users change the sensitivity bar, it cause the results this way:
If he drags it to the left, he will receive less results but they will be more accurate.
If he drags it to the right, he will receive more results, but they will be less accurate.
The current design does not convey the effect on the results when changing the sensitivity bar.
My question is: There is a way to pass to the users the idea that more results will come at the expense of accuracy in an efficient way?
