Techniques for correcting misspelled user queries of in-application searches are described as implemented by a user query processing system, which is configured to receive a user query entered via a search feature of an application, and identify a misspelled token in the user query. Candidate tokens to replace the misspelled token are identified from a collection of tokens, and a ranking of the candidate tokens is generated using machine learning. A token is selected from the candidate tokens based on the ranking, and the selected token is output by the user query processing system.
