I don't insist any such thing. A scraper site is a scraper site, whether it be a search engine, a directory, or just a useless list of links with AdSense stuck all over the pages.
By definition, a scraper site extracts snippets of text (and possibly URLs) from one or more websites and displays those results to visitors as a means to an end: making money. The use (or not) of a search box has absolutely no bearing on whether a site is a scraper or not. What determines whether a site is a scraper or not in based entirely on how it gets its content, not how is delivers it to the vistor.
Apparently you're failing to comprehend my posts.
