/// Creates a range query for the given field and bounds.

/// # JSON Numeric Range Queries and Fast Fields
///
/// For JSON fields, Tantivy requires fast fields for range queries (returns error otherwise).
/// Fast field storage has important limitations for JSON numeric values:
///
/// - Each JSON path gets ONE fast field column with ONE numeric type (I64, U64, or F64)
/// - Column type is determined at index time based on values stored:
///   - All integers that fit in i64 → I64 column
///   - All non-negative integers, some exceeding i64::MAX → U64 column
///   - Any float value OR mix of negative + large positive (≥ 2^63) → F64 column
/// - When column is F64, integers > 2^53 lose precision (e.g., 9007199254740993 → 9007199254740992.0)
///
/// At query time, Tantivy discovers the actual column type and converts query bounds accordingly
/// (see `search_on_json_numerical_field` in tantivy's range_query_fastfield.rs).
///
/// References:
/// - Fast field column type selection: tantivy columnar/src/columnar/writer/column_writers.rs
