zhengruifeng opened a new pull request, #57374: URL: https://github.com/apache/spark/pull/57374
### What changes were proposed in this pull request? Adds reciprocal `See Also` sections to related PySpark SQL built-in function docstrings: - Null and NaN predicates: `isnan`, `isnull`, and `isnotnull` - Null-handling functions: `nvl` and `nvl2` - SQL pattern and regular-expression matching functions: `like`, `ilike`, `rlike`, `regexp`, and `regexp_like` ### Why are the changes needed? Related functions and aliases are spread across the generated PySpark API reference. Cross-references make their different matching and null-handling semantics easier to discover and compare. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? No tests were added because this changes only API docstrings. Verified the staged diff with `git diff --check`. ### Was this patch authored or co-authored using generative AI tooling?
