Please do not use styles that are nonstandard, unusual, inappropriate or difficult to understand in articles, as you did in Elasticsearch. There is a Manual of Style, and edits should not deliberately go against it without special reason. Also please do not use misleading edit summaries. – NJD-DE (talk) 09:55, 2 May 2021 (UTC)
