Google Search
Google is a search engine for the world. The search results will include various possibilities of websites from all over the world, and the information sources will be more extensive. Of course, due to its regional considerations, in various countries around the world, Google’s search results also filter the results according to local corresponding laws. And Google’s intelligence is very high, the same language or region close to the user’s site search results will more easily occupy a higher ranking.
In addition, Google’s Scholar is a web search engine that can search academic articles for free. In November 2004, Google first released the BETA version of Google Scholar. The search covers most academic journals published in the world. It can help users find academic literature including journal theses, dissertations, books, preprints, abstracts and technical reports, covering natural sciences, humanities, social sciences and other disciplines. Because it does not provide any advertising links, its academic purity is very high. More uniquely, Google Scholar also includes academic research results that are not published online. For example, many of Einstein’s works have not been published online, but have been cited by many scholars.
