Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

Fig. 1 is a flowchart of a method for retrieval according to an embodiment of the present invention. As described in Figure 1, the method includes:

S101. Obtain a retrieval request.

S102. Determine whether the selected search server is available.

If it is judged to be unavailable when step S102 is executed, further execute step S103 to record the retrieval request. In an optional embodiment, the retrieval request is a retrieval request including a keyword, and the retrieval request is recorded to include one of the following: a keyword in the retrieval request is recorded; a retrieval request including a keyword is recorded; The URL of the retrieval request sent by the search server.

If it is determined that it is available when step S102 is executed, step S105 is further executed to send a search request to the search server.

After step S103 is executed, step S104 is further executed to re-determine whether the selected search server is available after a preset time interval.

If it is determined that it is available when step S104 is executed, step S105 is further executed to send a retrieval request to the search server, wherein the retrieval request refers to the retrieval request recorded in step 103 . If it is determined that it is not available when step S104 is executed, then return to continue to execute step S104.

After step S105 is executed, step S106 is further executed to receive the retrieval result sent by the search server.

An example of a method for retrieval according to another embodiment of the present invention is described below.

When searching through the browser side, that is, when the browser side receives a search request input through the input box of the browser and performs a search, it obtains the status of the selected search server based on the search request, and according to the obtained search server Status determines whether the search server is available.

In an optional embodiment, the search server selected by the user may be obtained according to the search request, and then a request is sent to the selected search server to obtain status information returned by the search server, so as to determine whether the search server is currently available.

In another optional embodiment, after the browser is started, a timer can be started at the same time to measure the time. After the preset time interval is measured, a request is sent to a preset search server to obtain status information returned by the search server. The timer can be reset after a preset time interval has been counted, and then restarted. In this way, a request can be sent to the search server every preset time interval to obtain the latest status information returned by the search server. These can be realized through the background of the browser. Then, it can be judged whether the search server is available according to the latest status information returned by the search server relative to the time of the retrieval request.

Taking the search server as google as an example, for example, the request initiated is: http://www.google.com.hk/search? q=AAAA, the search server returns information about the status of the request.

Some common status codes are: 200-the server successfully returns the web page 404-the requested web page does not exist 503-the server is temporarily unavailable.

Wherein, for the return status codes of 4xx (request error) and 5xx categories, the current status of the server may be considered as unavailable. For a detailed description of the above status codes, see: http://hi.baidu.com/wdown/item/a5598f7ac62b693e70442354

In a further optional embodiment, the browser background will first confirm the following three points: whether the computer has been connected to the Internet; whether the firewall configuration on the computer is correct; whether the portal website of the requested search server currently has technical problems. Among them, the confirmation of these three points by the browser background can be realized by querying the hardware and system configuration in the operating system. After confirming these three points, the browser sends a request to the selected search server to obtain the status information of the search server.

In the embodiment of the present invention, when it is judged that the search server is unavailable according to the state information fed back by the search server, the operation of recording the retrieval request is triggered. For example, the operation of recording the retrieval request may be to record keywords entered by the user in an input box of the browser (such as an address bar, a search bar, a webpage retrieval input box, etc.). In another embodiment, it is also possible to record the url of the retrieval request sent to google according to the input key, for example:

http://www.google.com.hk/search? q=%BC%D3%C4%C3%B4%F3&client=aff-360daohang&hl=zh-CN&ie=gb2312&newwindow=1.

Then, after a preset time interval, it is re-judged whether the search server is available. For example, in one embodiment, after the preset time interval, a request is sent to the aforementioned selected search server to obtain status information returned by the search server based on the request.

In the embodiment of the present invention, if the search server determines that the search server is available, the retrieval request is sent to the search server. Or, after a preset time interval, it is determined that the search service is available, and the recorded retrieval request is sent to the search server. If the search server is still judged to be unavailable after the set time interval, the step of re-judging whether the selected search server is available is continued at least once at the time interval until it is judged that the search server is available end.

Next, the search server will perform a search based on the search request and obtain corresponding search results. Then, the search server returns the search result to the browser side. In an optional embodiment, the returned retrieval results may be saved locally on the browser side for viewing by the user. In a further optional embodiment, the user is reminded that the retrieval result based on the keyword has been obtained. Referring to FIG. 2 , it shows a schematic diagram of an interface to remind the user after searching by using the method of the present invention and obtaining the search results. In this way, after receiving a message requesting a search result from a user, the search result will be displayed through a display interface. In an optional embodiment, if the user is not satisfied after viewing the search results, he can further modify the search keywords.

In another optional embodiment, after receiving the retrieval result from the search server, the retrieval result may be directly displayed through a display interface.

The present invention can save the search request input by the user when the search server is temporarily unavailable, so that the user does not need to input the search request again when the search server is available, which facilitates the reasonable and normal use of the search server by the user. In addition, since the browser side will judge whether the search server is available at regular intervals, the search results required by the user can be returned to the user in the fastest time.
