Summary
The attribute filters guide (user_guide/03-attribute-filters.qmd) demonstrates filter usage through examples but doesn't include a reference section listing all supported operators.
A user reading the guide can infer =, >=, AND, and IS NULL from the examples, but there's no way to discover the full set of available operators without reading the source code.
Suggested addition
A "Filter Operators" reference section listing:
Comparison operators (SQL-like string / dict AST):
= / eq, != / ne> / gt, >= / gte, < / lt, <= / lteIN / in, NOT IN / ninIS NULL, IS NOT NULL
Logical operators:
Dict AST structure:
{"type": "<operator>", "key": "<column>", "value": <value>}{"type": "and"|"or", "filters": [...]}
This could go between the current "Recap: Declaring Attributes" and "Built-In Backend Columns" sections, or as a new standalone section.
