Thanks for reaching here! You can use the speller parameter in your query request to enable spell checking in Azure Cognitive Search.
The speller parameter is supported for all query types: simple, full, and the semantic option currently in public preview.
To use spell check, you'll need the following:
- A search service at Basic tier or above, in any region. An existing search index with content in a supported language.
- A query request that has "speller=lexicon", and "queryLanguage" set to a supported language.
- Spell check works on strings passed in the "search" parameter. It's not supported for filters.
