Full-text search: The app supports searching full-text of all dictionaries for exact matches.

The scope of search is not limited to headwords and includes all text in all articles (definitions, synonyms, examples, etc). • Fuzzy search: Shows list of articles most similar to the query. The search works like a spell checker for words you're not sure how it's written/spelled. • Wildcard search: Shows list of articles that match the criteria set with a wildcard query.
