It's always exciting when a new version of RediSearch comes out — we just released version 1.4 (yes, we skipped 1.3 to align with a new versioning methodology). This new version has two key features which add quite a bit of smarts to querying:
- Spell Check and Custom Dictionaries.
- Phonetic (sound-alike) Matching.
Spell Check
