Load a query constructor runnable chain.
- Parameters:
llm (BaseLanguageModel) – BaseLanguageModel to use for the chain.
document_contents (str) – Description of the page contents of the document to be queried.
attribute_info (Sequence[AttributeInfo | dict]) – Sequence of attributes in the document.
examples (Sequence | None) – 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 (BasePromptTemplate | None) – Prompt for describing query schema. Should have string input variables allowed_comparators and allowed_operators.
fix_invalid (bool) – Whether to fix invalid filter directives by ignoring invalid operators, comparators and attributes.
kwargs (Any) – Additional named params to pass to FewShotPromptTemplate init.
- Returns:
A Runnable that can be used to construct queries.
