Is there a way to ensure no shared context is maintained between calls, and every api call to ollama is treated as independent ?

Is there a way to ensure no shared context is maintained between calls, and every api call to ollama is treated as independent ?

I am making a RAG app using milvus db and Ollama's llms. I have the api for this functions - upload(Takes pdf and indexes it in milvus), /query(Search from a particular db). I want to include chat history functionality as well how to achieve this ?
