What is the purpose of setting a fuzziness level during a dictionary search?

Setting a fuzziness level during a dictionary search primarily serves to determine the degree of variation in the terms returned. This concept allows for the inclusion of similar terms that might not precisely match the query but are close in spelling or meaning. By allowing for a fuzziness level, the search can return results that accommodate typographical errors or different variations of a word or phrase, thus enhancing the thoroughness of the search.

For example, if a user is searching for "relativity" and the fuzziness level is set to 1, the search may also consider terms like "relataviy" or "relativity." This flexibility ensures that searches are not overly strict and can yield useful results even when the exact term isn’t used, enhancing user satisfaction and effectiveness in finding relevant data.
