different search method

[patser]

hello,

at the moment, im looking for a way to let my customers do the following:

ex: my products have different sizes: 20, 40, 60 and 80 cm.

if someone searches for 60 cm, the search engine should list 20, 40 and 60 cm -> all products up to the searched size.

is there a way to do that?

thanks for help
