Analysis of different search results for the same time in the same region as Baidu search

At this moment, Baidu search results, you are different? May 13 at this moment, Baidu search, I am different.

13th morning on the 11 point when the plum screenshot (see figure I) said to me: "Baidu search under the sprinkler, you see today's Baidu Drop-down box appeared such as two words, sprinkler clxyk, sprinkler car zycok." "I replied," she said, "I didn't find it at nine in the morning." "Now there, you look again." "Ah, this Baidu update is fast enough, I thought, and Baidu search" sprinkler ", the result is not, let me a little strange, see figure II

　　

　　

What the hell is going on here?

Think one: Do you really have the same area and the same time the results of the search for a different situation?

Different areas of the search results may not be the same, the same region and the same time search results can not be the same? (I and Mei with the city, less than two kilometers apart), will exist in the same region and the same time the results of the search is not the same? is the reason for computer caching? I remote to Meiqing in addition to the computer cache after the search still appeared figure a result, will be their own computer caching reasons? I immediately cleared my own computer cache, The result of Figure II that still appears, eh? Think about, let Mei restart after search, and then change the browser search, for a while she replied to the search results are still figure one, let Mei operation at the same time I also restarted the computer search, respectively for Google browser, Firefox browser search again, my search results are still figure ii. I have come to the conclusion that the same region and the same time the results of the search for a different situation.

Think 2:100 degrees really have the ability to identify user search habits?

What causes the same region and the same time to search for different results? I fell into a deep thinking, a friend told me that maybe Baidu has the ability to identify user search habits, that is, a computer often on those sites, in search of time, those sites will be ranked in front, is this it? Does Baidu really have the ability to identify user search habits? I'm confused. I told Mei the reason. In a moment, Mei replied, "I used my other computer to search it out, too." Sprinkler Clxyk, sprinkler zycok that two keywords, my other computer has not been searched before, I let my friend search, and my brother search, the results are there, they did not search this before. "See Mei's information, I also immediately changed a computer, just sister's computer put me here has not taken away, her computer is not previously searched the sprinkler car, I use my sister's computer test, search results are still figure two, and plum is not the same

It seems that the search results are not the same reason Baidu has to identify the search user search habits, then, in the end is what? Think again, only the IP is different, may use is telecommunications, I use is also telecommunications, only IP is different

Think three. Does the IP difference cause the same region to search for the same time as a different result?

Contacted a friend who has done IDC. He definitely told me that the same area of the same time different IP different lines can lead to different search results.

Originally Baidu is not to say that we directly visit his server, we visit only it in the country's mirror server, such as: The middle is the core of Baidu server, the core of the network fork, that is the mirror server, other blue small circle is the user.

　　

User access to mirror server has multiple paths, as shown in

　　

User to access the top core server access to the mirror server one or two or three ...

Baidu has a number of mirror servers, a region at least one telecom mirror server a netcom mirror server. The latest data is all on the core server, the core to get the data to update the mirror server, the general image is updated with the core server, unless there is a problem or delay.

I searched and watched, and by 4:28 P.M., when I searched the sprinklers again, the search results were the same as plum, as pictured. Oh, it seems that I and Mei appear different search results are access to the mirror server, and I was in the mirror server may be out of the question or is the update delay.

The above is I for the same region and the same time to search out the results of the analysis, we have any different views? Welcome to the brick, please correct me!
