Reviving phonetic algorithms for better search relevance
summary
Reimplements century‑old phonetic encoders and benchmarks them against Levenshtein fuzziness on a huge French audiovisual index, finding phonetic matching cuts noise where fuzzy edit distances swamp results. Uses Beider-Morse, Soundex and Metaphone encodings, indexes phonetic tokens alongside lexical fields, routes by language, and boosts exact and phonetic matches. Integration uses an OpenSearch connector to call an external phonetic service. Recommendation: do not apply fuzziness to phonetic keys.
