RediSearch 1.4: Phonetics & Spell Check

RediSearch 1.4 introduces two key features that enhance querying capabilities: spell check and phonetic matching. Spell check uses a primitive to power a "did-you-mean" feature, identifying misspelled words and suggesting corrections. Phonetic matching solves the canonical problem of searching for similar names by using an algorithm called Double Metaphone, which breaks down text into language-specific codes based on pronunciation rules. These features add flexibility to search while accommodating human error without losing sight of user intention.
