A Correct answer
Explanation

Metasearch engines (like Dogpile, Metacrawler) do not maintain their own database. Instead, they forward user queries to multiple search engines simultaneously and aggregate the results. Webcrawlers and spiders are automated programs that browse the web to index pages, while 'hits' refers to search results, not a search tool.
