Fuzzy matching techniques are used to find partial matches on strings, but they can be performance-intensive. YugabyteDB provides several alternatives for fuzzy matching, including Levenshtein distance, Soundex, Metaphone (or double Metaphone), and trigram extensions. The most performant method is the indexed double metaphone approach, which reduces time spent on queries significantly. Trigram searches are more accurate but slower. By combining the speed of metaphone with the precision of trigrams, YugabyteDB users can achieve the best results for fuzzy matching tasks.
