For quickstart, we can reply on the default prompt engine configurations. Here we are using default templates for the queries. We can select these templates using the PromptTypeEnum enum. The available templates are:
PromptTypeEnum.CONTEXTUAL_QA_PROMPT
PromptTypeEnum.CONTEXTUAL_CHAT_PROMPT
PromptTypeEnum.SIMPLE_CHAT_PROMPT
The prompt engine validates the query by default. If the query is not valid, it raises a ValueError exception and will not return any prompt template. Model is a required component for the prompt engine inorder to validate the query. If the model is not provided, the validation will fail.
