描述

Creating a grouing query string (e.g. all( group(customer) each(output(sum(price))) ) ) can be difficult with multi-level grouping, having a UI to construct the string a la the querybuilder might help.

Can be useful as a validator, too - paste a string into a field, and auto-generate an pretty-printed view

hence both ways from structured to string and vice versa

see #16870 for implementation suggestion

研究方向
First, review the referenced issue #16870 for implementation suggestions. Then, examine existing Vespa query builders or similar tools to understand the grouping query syntax. Consider prototyping a simple UI component that allows building grouping strings interactively and validating them. Look at Vespa's documentation for grouping syntax to ensure correctness.
