The corresponding relationship of search result information and the identification information and the source regional information.
Below by specific embodiment, the present invention is described in detail.
Fig. 1 is a kind of flow diagram of the caching method of video search result information provided in an embodiment of the present invention, can
To include:
S101: the searching request that user is directed to target video is obtained.
It will be appreciated by persons skilled in the art that including at least the source place of described search request in described search request
The identification information of domain information and the target video.The source regional information can be for user's in described search request
IP address；The identification information of the target video refers to the information that can identify target video, is specifically as follows target video title
Identification information Deng, the target video can be search key, search limitation parameter etc. in described search request.Example
Such as, the user of region Y has sent the searching request of video A, then the source regional information of the searching request is region Y, target
The identification information of video is video A.
S102: according to described search request and preset regional information group, judge whether wrap in the regional information group
The source regional information is included, if so, executing S103.
Wherein, the regional information group is for target video, and the region for the not right of broadcasting for counting and being arranged in advance is believed
Breath.A regional information is included at least in the regional information group.It will be appreciated by persons skilled in the art that the region letter
Breath group includes currently known the regional information either with or without right of broadcasting.
In practical applications, currently known the regional information either with or without right of broadcasting, and handle can be manually counted in advance
These regional informations are set as regional information group.
For example, being directed to video A, the region of currently known not right of broadcasting is only Y and Z, therefore preset regional information group
For region Y and Z.The source regional information for obtaining searching request through S101 is region Y, then according to searching request and preset
Regional information group judges to include the source regional information in regional information group.
S103: according at least to the identification information and the source regional information, search whether in the buffer exist with
The identification information and corresponding first search result information of the source regional information, if it does not, executing S104.
Wherein, first search result information is the search for target video fed back to the region of not right of broadcasting
Result information.
For example, being directed to video A, S102 judges to include source regional information (in regional information group (region Y and Z)
Domain Y), then searching whether that having corresponding with video A and region Y first searches in the buffer according to video A and region Y
Rope result information.
S104: described first is searched in non-caching area according at least to the identification information and the source regional information
Search result information.
It will be appreciated by persons skilled in the art that the non-caching area can be memory, it is also possible to hard disk etc., this hair
It is bright to be not specifically limited herein.
S105: first search result information is stored in the caching.
S106: first search result information and the identification information and the source regional information are at least established
Corresponding relationship.
It will be appreciated by persons skilled in the art that the corresponding relationship can store in the buffer, also can store
In non-caching area, the present invention is not specifically limited herein.
For example, being directed to video A, S103 lookup result is that there is no then look into non-caching area according to video A and region Y
The first search result information is looked for, the first search result information found is labeled as AY, in the buffer by AY storage, and is built
The corresponding relationship of vertical AY and video A and region Y.
Assuming that the searching request for the video A that the user that server obtains region Z at this time sends, judges regional information group again
In include region Z, according to video A and region Z, search that there is no the first search corresponding with video A and region Z in the buffer
Then result information searches the first search result information corresponding with video A and region Z, by what is found in non-caching area
First search result information is labeled as AZ, and in the buffer by AZ storage, and it is corresponding with video A and region Z to establish AZ
Relationship.
In this way, when the video A searching request that the user that server is received again by region Y sends, so that it may in the buffer
First search result information AY corresponding with video A and region Y is found, the AY in caching is fed back into user；Similarly, work as service
When the video A searching request that the user that device is received again by region Z sends, so that it may find in the buffer and Z pairs of video A and region
The the first search result information AZ answered, feeds back to user for the AZ in caching.Because AY and AZ may be identical, it is also possible to it is different,
So storing AY and AZ respectively in the buffer, in this way when corresponding searching request is come, server can be transferred in caching respectively
AY and AZ, thus give the accurate information of user feedback；And due to being cached, so when next same search is asked
Ask come it is interim, server can directly from caching gathering information, improve feedback speed, and reduce looking into non-caching area
Look for number.
It in practical applications, can also be first according at least to preset region before searching request arriving for target video
The identification information of regional information and target video in information group searches the identification information with target video in non-caching area
And the corresponding search result information of regional information in default regional information group, which is stored in caching
In, and at least establish the regional information in the identification information and default regional information group of the search result information and target video
Corresponding relationship.In this way, interim when there is corresponding searching request, so that it may the corresponding information in caching is directly found, by this
Information feeds back to user, to further improve the feedback speed of server.
As seen from the above, using embodiment illustrated in fig. 1 of the present invention, server is according to the identification information and the source
Regional information has carried out first search result information to distinguish storage in the buffer, so when next corresponding search is asked
It asks and comes temporarily, server can directly transfer corresponding information from caching, improve the speed and accuracy of feedback information, and reduce
Lookup number in non-caching area to reduce the pressure of server improves the energy of server process searching request
Power.
In the aforementioned embodiment, there is also the situations that judging result is no by S102.Based on foregoing description, of the invention one
In kind specific implementation, referring to fig. 2, the flow diagram of the caching method of another video search result information is provided,
Compared with previous embodiment, in the present embodiment, can also include:
S107: when S102 judging result be it is no when, according to the identification information, search whether in the buffer exist with it is described
Corresponding second search result information of identification information, if it does not, executing S108.
Wherein, second search result information is the search knot for target video fed back to the region for having right of broadcasting
Fruit information.
For example, being directed to video A, region X has right of broadcasting, and region Y does not have right of broadcasting, and region Z is preset also without right of broadcasting
Regional information group is region Y and Z.The searching request that video A is had sent with user orientation server of region X, obtains this through S101 and searches
The source regional information of rope request is region X, and the identification information of target video is video A；Judge in regional information group through S102
It does not include region X；So according to video A, search whether there is the second search result information corresponding with video A in the buffer.
S108: second search result information is searched in non-caching area according to the identification information.
S109: second search result information is stored in the caching.
S110: the corresponding relationship of second search result information and the identification information is established.
For example, being directed to video A, S107 lookup result is that there is no then search second according to video A in non-caching area and search
Rope result information in the buffer by the second search result information found storage, and establishes second search result information
With the corresponding relationship of video A.
Because being directed to video A, for the user of all regions for having right of broadcasting, the search result information of server feedback is
It is identical, so server need to only store second search result information in the buffer.Assuming that being directed to video A, region W
Also there is right of broadcasting, then the video A search that the user of video A search result information and region X that the user of region W obtains obtains
Result information should be identical.So when the searching request for the video A that the user that server obtains region W sends again,
Judge not including region W in regional information group, then according to video A, searches the second search result corresponding with video A in the buffer
The second search result information found is fed back to user by information.In fact, server is the region X that will be cached before
Video A search result information has fed back to the user of region W, but because the two search result informations be it is identical,
Server feedback is accurate information.
Server stores the first search result information and the second search result information respectively in the buffer, and according to source
Regional information has carried out corresponding first search result information to distinguish storage.In this way, the user as region X or region W sends out
When sending video A searching request, server can transfer the second search result information in caching, by second search result information
Feed back to user；And when the user of region Y send video A searching request when, server can transfer caching in video A and
The corresponding first search result information AY of region Y, feeds back to user for AY；When the user of region Z sends video A searching request
When, server can transfer first search result information AZ corresponding with video A and region Z in caching, and AZ is fed back to use
Family.
As seen from the above, using embodiment illustrated in fig. 2 of the present invention, not only can be improved server feedback information speed and
Accuracy, and since server only stores second search result information, so having saved the memory space of caching, mention
High resource utilization.
In practical applications, the platform for playing video can also have right of broadcasting, for example, being directed to video A, computer webpage
There is right of broadcasting at end, and mobile phone applications client does not have right of broadcasting.
It further include described search in described search request in an alternate embodiment of the present invention where based on foregoing description
The platform information of request；Shown in Figure 3, embodiment illustrated in fig. 3 of the present invention can also include: compared with embodiment illustrated in fig. 1
S111: it when S102 judging result is no, according to the identification information and the platform information, looks into the buffer
It looks for the presence or absence of third search result information corresponding with the identification information and the platform information；If it does not, holding
Row S112.
Wherein, the third search result information is to be fed back to the platform and the region for having right of broadcasting for target
The search result information of video.
S112: the third search result is searched in non-caching area according to the identification information and the platform information
Information.
S113: the third search result information is stored in the caching.
S114: the corresponding pass of the third search result information with the identification information and the platform information is established
System.
For example, being directed to video A, region X and W have right of broadcasting, and region Y and Z do not have right of broadcasting.The computer page end of region X
User have sent the searching request of video A, S101 obtains the searching request；It wherein, include that search is asked in the searching request
Source regional information (region X), the platform information (computer page end) of searching request and the identification information of target video asked
(video A)；S102 judges that in preset regional information group (region Y and Z) do not include the source regional information, then according to view
Frequency A and computer page end search whether there is third search result corresponding with video A and computer page end in the buffer
Information, if it does not exist, then third search result information is searched in non-caching area according to video A and computer page end, it will
The third search result information storage found in the buffer, and establish the third search result information and video A and
The corresponding relationship of computer page end.So when the search that the user of the mobile phone applications client of region X equally has sent video A is asked
When asking, according to video A and mobile phone applications client, it will search less than matched information in the buffer, it is therefore desirable to non-slow
It deposits in area and searches again, obtain corresponding search result information, and in the buffer by search result information storage.And work as region
When the user of the computer page end of W equally has sent the searching request of video A, according to video A and computer page end, caching
It is middle to find matched information.It should be noted that the third search result information can be with second search
Result information is identical, can also be different from second search result information.
The S103 of embodiment illustrated in fig. 3 of the present invention is specifically as follows S103A: according to the identification information, the source place
Domain information and the platform information, search whether in the buffer exist with the identification information, the source regional information with
And corresponding first search result information of the platform information；If it does not, executing S104；
The S104 of embodiment illustrated in fig. 3 of the present invention is specifically as follows S104A: according to the identification information, the source place
Domain information and the platform information search first search result information in non-caching area；
The S106 of embodiment illustrated in fig. 3 of the present invention is specifically as follows S106A: establishing first search result information and institute
State the corresponding relationship of identification information, the source regional information and the platform information.
It will be appreciated by persons skilled in the art that server feedback is searched when sending the platform difference of searching request
Rope result information may also be different.So in the present embodiment, when being searched in caching and non-caching area, in addition to according to the mark
Other than information and the source regional information, it is also necessary to according to the platform information, search first search result information；
Correspondingly, when establishing corresponding relationship, it is also desirable to establish first search result information and the identification information, the source
The corresponding relationship of regional information and the platform information.
For example, the user of the computer page end of region Y has sent the searching request of video A, S101 obtains the search and asks
It asks；Wherein, the platform information (computer in the searching request including the source regional information (region Y) of searching request, searching request
Page end) and target video identification information (video A)；S102 judges
The source regional information (region Y), then searching whether to deposit in the buffer according to video A, computer page end and region Y
In the first search result information corresponding with video A, computer page end and region Y, if it does not exist, then according to video A, electricity
Brain page end and region Y search the first search result information in non-caching area, the first search result information that will be found
Storage in the buffer, and establishes the corresponding relationship of first search result information and video A, computer page end and region Y.
So when the user of the mobile phone applications client of region Y equally has sent the searching request of video A, answered according to video A, mobile phone
With client and region Y, will search in the buffer less than matched information, it is therefore desirable to it is searched again in non-caching area,
Corresponding search result information is obtained, and in the buffer by search result information storage.
As seen from the above, using embodiment illustrated in fig. 3 of the present invention, for target video, server only stores each flat
One third search result information of platform improves resource utilization so having saved the memory space of caching；And server
The search result information of different platform has been carried out to distinguish storage, can be further improved the accuracy of feedback information.
It will be appreciated by persons skilled in the art that may include not no right of broadcasting in first search result information
Regional information.Wherein, the regional information of right of broadcasting not can be for video A, be also possible to for other videos, example
As and the higher video B of video A correlation.
