In the "search options" launched by Google in May, there is a function that restricts search results by time, you can search by default for "anytime", "last year", "last week", "last", or "last 24 hours". However, this is still quite different from "real-time. Google cannot provide search within the past minute or even one second. However, you can add parameters to the search URL to shorten the time.
Search for content about Barack Obama in the past 24 hours
For example, search for content about Barack Obama in the past 24 hours:
Http://www.google.com/search? Q = barack % 20 obama & hl = en & output = search & tbs = qdr: d & tbo = 1
Note that the parameter "qdr: d" indicates that "qdr" is the abbreviation of "Query Date Range" (search time Range). Therefore, we change the parameter to "qdr: d: n "searches for the content in the past minute, and changes the content in the past second to" qdr: s ". That is:
Search results for the past minute
Last minute:
Http://www.google.com/search? Q = barack % 20 obama & hl = en & output = search & tbs = qdr: n & tbo = 1
In the past one second, the search result is zero because the time is too short.
Last one second:
Http://www.google.com/search? Q = barack % 20 obama & hl = en & output = search & tbs = qdr: s & tbo = 1
No content was found in the last second. This is not surprising, because the time value is too small, only 1 second.
In addition, you can search for the content in the past hour:
Http://www.google.com/search? Q = omgili & hl = en & tbo = 1 & tbs = qdr: h
Or you can search for the content in the past 10 minutes:
Http://www.google.com/search? Q = barack % 20 obama & hl = en & output = search & tbs = qdr: n10 & tbo = 1
Or you can search for the content in the past 30 seconds:
Http://www.google.com/search? Q = barack % 20 obama & hl = en & output = search & tbs = qdr: s30 & tbo = 1
In fact, you only need to add a number after the time parameter (h represents the hour, n represents the minute, and s represents the second), for example, "qdr: n10 to return the search results in the past 10 minutes.
