Search results combined from custom fields

Hi,
I am looking for a possibility to combine multilpe values from the custom field into one search option.
For example.
I have multiple distances (numerics) and I prefer to use a range slider.
In this case the distances are 70, 100, 130, 160 and 200. If the visitor of the website use a range slider and have settings from 100 - 160 I want to ensure that the outcome will be distances between 100 till 160.

All kind of suggestion are welcome.
