What is the difference between a PC-side search and a mobile search?

I think the difference between mobile search and non-mobile search (traditional search, Baidu, Google for example) is better.
Important point: Mobile search refers to the people in the mobile scene of the search, mobile devices just to provide conditions for this scenario.

The purpose of the search is to establish connections, and compare mobile search and traditional search methods to differentiate between the connections they are establishing.

Connected objects
Traditional search connects people to relative static information, search results are affected by user time and space, while mobile search connects people and relative dynamic information, search results are affected by user time and space.
How connections are built
Traditional search is carried out in a secure environment, where the user can stay focused and perform a detailed selection of results, while mobile search takes place in an outdoor environment where users need to use gestures, sounds, sensors and more to get results quickly.
Connected consumption mode
This is the main difference, the traditional search results are directly consumed by the user, the consumption method is relatively limited. For example, watching news, watching movies, buying things, etc. In the mobile search, the search results need to guide users how to consume it, for example, after searching the hotel needs to instruct the user to order a meal, search after the hotel needs to stay in the operation, search to the destination needs navigation and so on. Different search results require different ways of spending. These rich mobile consumer experiences are the real changes that mobile search brings.

1 Web search input keywords, output web links, the answer to find their own, users feel very natural, or have been accustomed to;
2 mobile search can input text, voice, photos, geographical location, input source may be more, the output of a variety, anyway, not the same feeling is natural;
3 If you look at the input and output from the point of view, almost all of the input, through the dialog box output acceptance is also high, most likely the way to move the search later.
Other mobile search methods, have not seen too reliable.
