AzureCognitiveSearchChatExtensionConfiguration using Semantic Search reduces the number of document results

Question

Hello!

I am using AzureCognitiveSearchChatExtensionConfiguration to add context to chat mode:

 AzureCognitiveSearchChatExtensionConfiguration cognitiveSearchOptions = new()             
	{                 
		DocumentCount = 12,
        EmbeddingEndpoint = new Uri(apiEmbeddingEndpoint),                 
		SearchEndpoint = new Uri(searchEndpoint),                 	        
		IndexName = searchIndexName,                  
		QueryType = AzureCognitiveSearchQueryType.VectorSemanticHybrid,
   		SemanticConfiguration = "default"             
	};

If I use QueryType VectorHybrid it uses the correct document count, but when I activate VectorSemanticHybrid the number of results used in the context is lower than 12.

How can I configure the Semantic Search to only rerank the documents but not lose documents in the process?

Thank you

Hi @Juan Velázquez Romera

Welcome to Microsoft Q&A! Thanks for posting the question.

Can you please provide details how are you checking the number of documents is less than 12 ? Please include a screenshot if possible.

Also, can you please try setting the ShouldRestrictResultScope property to false if this works?

Thanks
