Which of the following is an example of a meta search engine?

• A. Startpage, eTools.ch and MetaGer
• B. Google, Bing, Yahoo
• C. Shodan
• D. TinEye

Answer: (A)

Meta search engines work by sending your query to multiple search engines and then aggregating the results into one list. They don’t build or maintain their own separate index; instead, they rely on the indexes of several engines to return combined results. Startpage, eTools.ch, and MetaGer fit this pattern because they pull data from multiple sources and present a unified set of results. The other examples aren’t meta search engines. Google, Bing, and Yahoo are individual search engines with their own indexes. Shodan specializes in crawling and indexing the internet for internet-connected devices, not aggregating results from multiple engines. TinEye focuses on reverse image search using its own image index.
