Is the issue that you don't know how to call the methods (which the
documentation shows), or that you don't know what and how to implement
a fuzzy search? The gem is giving you the means to calculate
"distance" between two strings (the algorithm is named "Jaro-Winkler"
which is the measure of similarity between two strings, c.f.
https://en.wikipedia.org/wiki/Jaro%E2%80%93Winkler_distance), from
that you can choose how much "fuzziness" to apply, which can be highly
domain-specific.
