Load a query constructor chain.
- Parameters
llm (BaseLanguageModel) – BaseLanguageModel to use for the chain.
document_contents (str) – The contents of the document to be queried.
attribute_info (Sequence[Union[AttributeInfo, dict]]) – Sequence of attributes in the document.
examples (Optional[List]) – Optional list of examples to use for the chain.
allowed_comparators (Sequence[Comparator]) – Sequence of allowed comparators. Defaults to all Comparators.
allowed_operators (Sequence[Operator]) – Sequence of allowed operators. Defaults to all 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) – Arbitrary named params to pass to LLMChain.
- Returns
A LLMChain that can be used to construct queries.
- Return type
