Create query construction prompt.
- Parameters
document_contents (str) – The contents of the document to be queried.
attribute_info (Sequence[Union[AttributeInfo, dict]]) – A list of AttributeInfo objects describing the attributes of the document.
examples (Optional[Sequence]) – Optional list of examples to use for the chain.
allowed_comparators (Sequence[Comparator]) – Sequence of allowed comparators.
allowed_operators (Sequence[Operator]) – Sequence of allowed operators.
enable_limit (bool) – Whether to enable the limit operator. Defaults to False.
schema_prompt (Optional[BasePromptTemplate]) – Prompt for describing query schema. Should have string input variables allowed_comparators and allowed_operators.
**kwargs (Any) – Additional named params to pass to FewShotPromptTemplate init.
- Returns
A prompt template that can be used to construct queries.
- Return type
