Search Reddit posts/comments or read a full comment thread — reads the Arctic Shift community archive (reddit.com blocks direct scraping). A scoped search (subreddit or author) queries the archive directly. A Reddit-wide keyword search finds posts with a site-restricted web search and then reads those posts from the archive — or, in comments mode, searches each of the first five posts' comments for the keywords — because Arctic Shift cannot keyword-search across all of Reddit. A scoped comment search Arctic Shift times out on is retried over the last 7d and 3d and reports window_applied. Arctic Shift is tried first and PullPush (api.pullpush.io) second: when Arctic Shift or the web-discovery path fails a posts or comments search, PullPush is queried and the response reports fallback_used. PullPush has refused automated clients since August 2026, so that fallback usually reports its refusal too.
