What is the gap between Baidu and Google search engines?

 

What is the gap between Baidu and Google? The search engine needs to manage the captured results. When there are more and more index results, it is more and more difficult to ensure the storage and query speed and ensure the consistency of the content of tens of thousands of servers. Google published three papers around and described three technologies, GFS, BigTable, and MapReduce, to solve these problems. Google did not publish algorithm details, so Yahoo took the lead and established the open-source project Hadoop in about 06 years. The goal was to implement a large-scale management and computing system based on three Google papers. However, the gap between Hadoop and some key indicators published by Google remains several times in the past 08 years. Baidu was once led by a doctor from Academician Wang Xuan and wanted to implement its own system independently (pyramid program) based on Google Papers. However, the project was too difficult to develop and finally switched to Hadoop. Today, Amazon, Facebook, Yahoo, and Baidu are all using Hadoop on a large scale, and Google has migrated to the new trigger Caffeine, Pregel, and Dremel since 2010. In terms of single search technology, Google is not leading Baidu, but the world.

.. Google announced the world's first global database system Spanner, which connects data centers distributed around the world and uses atomic clocks and GPS to break the geographic gap, it provides a global database with consistency and real-time performance. Before Google, many people thought that such a system could not be made, but Google did.

... In addition to search, Google is also the world's leader in deep learning and robotics, especially the latter. Although Baidu also has a deep learning research institute, these two aspects are completely blank compared with Google.

... In fact, it is unfair to compare Baidu with Google. Search is only a department of Google, but a whole company of Baidu. Google's competitors include Apple, Amazon, Facebook, and Microsoft. Baidu's competitors include 360 and Sogou. Google has no search, Chrome, Android, Youtube, and Baidu.
