Basically a boolean search automation. Gets HTML code of URLs found by a prompt you enter and gets anything that matches an email regex in the code. Exports a .csv file with columns: query, email, link (where an email was found). Advantages: all emails found are 100% real. Disadvantages: may find emails not related to the subject if to search buy just a keyword instead of link.
[1] - parsing by single prompt [2] - parsing by multiple prompts from .csv file. Reads the first column of the file [s] - search engine switch: Google API (requires Google custom SE API key and SE ID), DuckDuckGo [p] - prompt mode: '"Keyword"' - better for words, 'site:keyword.com' - better for links, both - both variants, but 2 times more prompts, so works more slowly and more likely to meet search engine limitations
