You can perform a search over an NGRAM TEXT index by matching the n-grams of the text value in the CONTAINS clause of the query against the stored n-grams in the index.
NGRAM TEXT index accommodates fuzzy searching capability over the text for both European and non-European languages.
NGRAM term breaker is built on TEXT indexes, so use text configuration object settings to define whether to use an NGRAM or GENERIC TEXT index.
