   I checked the live issue and the current `apache/doris-website` source. The 
report looks valid and is a documentation consistency issue, not a Doris 
runtime issue.
   
   In the English versioned docs, both affected files contain the same mismatch:
   
   - 
`versioned_docs/version-2.1/sql-manual/sql-functions/aggregate-functions/group-array-intersect.md`
   - 
`versioned_docs/version-3.x/sql-manual/sql-functions/aggregate-functions/group-array-intersect.md`
   
   The first example runs:
   
   ```sql
   select c_array_string from group_array_intersect_test where id in (18, 20);
   ```
   
   but the displayed result is a two-column `id | col` table with rows `1`, 
`2`, and `3`. That output cannot come from the shown SQL because the select 
list, column name, and filter all disagree with the result table.
   
   The suggested narrow fix is reasonable if the 2.1/3.x setup PRs keep the old 
example schema with a column named `col`:
   
   ```sql
   select id, col from group_array_intersect_test;
   ```
   
   That would make the first example match its displayed output and keep the 
second example, `select group_array_intersect(col) from 
group_array_intersect_test;`, internally consistent.
   
   One scope note: the same stale snippet also exists in the zh-CN and ja 
versioned copies for 2.1 and 3.x. If the docs PR updates localized snapshots 
directly, those copies should be aligned as well; otherwise they can follow the 
normal localization sync process.
   
   No query logs, profiles, or Doris version-specific runtime evidence are 
needed to confirm this issue. The only thing to decide before merging a patch 
is the canonical example schema for these older pages: keep the old `col` 
schema and apply the narrow SQL correction above, or backport the current/4.x 
style setup that uses `c_array_string` throughout.
