This showcase uses Typesense's typo-correction feature to build a Type-Ahead Spellchecker.
We index 333K dictionary words, along with the popularity of each word in a Typesense collection. We then extract the last typed word and send it as a "search" to Typesense. Since Typesense searches for typo-corrected words automatically, it returns closely related typo-corrected words from the dictionary, which we show as type-ahead suggestions.
The search backend is powered by a single-node 512MB RAM Typesense Cloud cluster in Oregon.
