Azure Cognitive Search - Spell Checker Implementation in C#

Question

I am looking for implementing spell checker for the azure cognitive search in C#. For now I have reviewed the spell checker link from the official Microsoft documentation:

https://learn.microsoft.com/en-us/azure/search/speller-how-to-add

But there's no code snippet or example that demonstrates the use in C#. The link does say we need to pass the parameters like "speller=lexicon" and "queryLanguage=en-us" with the search API call.

I have a basic search implemented for Azure Cognitive search. Please refer the below code snippet:

// Configures the 'SearchParameters' object
        SearchParameters searchParams = new SearchParameters
        {
            Skip = (page - 1) * PAGE_SIZE,
            Top = PAGE_SIZE,
            IncludeTotalResultCount = true,
            Facets = Facets
        };

        // Returns all results on initial page load
        string searchString = "*";
        if (!string.IsNullOrEmpty(searchText))
            searchString = searchText;

        // Performs a search request on the specified Azure Search index with the configured 'SearchParameters' object
        DocumentSearchResult<Document> result = searchIndexClient.Documents.Search(searchString, searchParams);

But the "SearchParameters" have no properties of passing the "speller" and "queryLanguage" parameters to get the result for spell checker. Please review the screenshot below:

Can anyone suggest for the "spell checker" for code implementation in C#?

Hi @sachin sipl my apologies for the late response. I have been out of the office for the past few days. The ACS team said since this feature [Spell Checker] is still in preview, it is only available through the Azure portal and REST API only as per: Add spell check to queries - Azure Cognitive Search | Microsoft Learn. You would have to call directly the API vs using a specific language call in order to implement it as of right now.

Hope that helps. Please let us know if you have further questions.

Thanks!
