Changelog
naver-blog/search is a hard-breaking contract standardization. The operation no longer exposes upstream-shaped public input fields (display, start, sort) or upstream-shaped output fields (link, bloggername, bloggerlink, postdate, meta, or lastBuildDate).
Replace display with limit, start with offset, sort with sort_by values relevance/date, and read normalized blog fields such as url, blogger_name, blogger_url, published_date, and summary.
