And may even be implemented as a server, such as a file server, a database server, an application server, a WEB server, and so forth. The embodiments of the present invention are not limited thereto.

In an embodiment in accordance with the invention, the computing device 100 is configured to perform a mail search method 200 in accordance with the invention. Among other things, the application 122 of the computing device 100 contains a plurality of program instructions for executing the mail search method 200 of the present invention, which can be read and executed by the computing device 100, so that the computing device 100 executes the mail search method 200 according to the present invention.

In one embodiment, mailbox client 300 is included in application 122 of computing device 100, and mailbox client 300 contains a plurality of program instructions for performing mail search method 200 of the present invention, such that mail search method 200 of the present invention may be performed at mailbox client 300.

As shown in fig. 2, the method 200 begins at step S210. In step S210, a search request for the mail from the user is received, and search information and a search list are determined according to the search request. Here, the search information is, for example, character string information. The search directory may include one or more file directories, and each file directory may include one or more mails.

According to one embodiment, the mailbox client may include one or more mailbox account nodes, and each mailbox account node may include one or more file directories, such as file directories including an inbox, a draft box, sent mail, deleted mail, and the like, but is not limited to those listed herein. The search directory based on which the user sends the search request for the mail may be a directory corresponding to any mailbox account node, that is, the user may search the mail based on the search information under the mailbox account node. For example, a user selects a mailbox account node on a mailbox interface, inputs search information to a search column in the mailbox interface under the mailbox account node to send a search request to a mailbox client, the search request acquired by the mailbox client includes the search information and search directory information corresponding to the mailbox account node, and the search directory includes all file directories under the mailbox account node.

Subsequently, in step S220, the total number of mails included in the search list is determined, and it is determined whether the total number of mails is greater than a first threshold. Here, the total number of mails included in the search directory is the sum of the numbers of mails in each file directory included in the search directory, that is, the sum of the numbers of mails in all file directories under the corresponding mailbox account node.

It should be noted that the first threshold may reflect whether the total number of mails in the search directory is too much to meet the search condition of the mails with large data volume, and a search mechanism for the mails with large number needs to be adopted. When the total number of the mails is larger than the first threshold value, the total number of the mails is determined to be in accordance with the mails with large data volume, and a searching mechanism aiming at the mails with large data volume needs to be adopted, and further, the following steps S240 to S260 are executed to realize the searching of the mails with large data volume.

If it is determined that the total number of mails is greater than the first threshold, step S230 is performed. In step S230, a thread pool is created that includes one or more threads. In this way, a thread pool may be invoked to conduct a search for large data volume mail using one or more threads. Here, the invention is not limited to the specific number of threads in the created thread pool, which may be determined according to the configuration of the computing device.

It should be noted that the present invention is not limited to specific values of the first threshold. In one embodiment, the first threshold is 6000, but the invention is not limited thereto.

Subsequently, in step S240, each file directory included in the search directory is traversed in a loop, and for each file directory included in the search directory, one or more task objects are respectively created according to the mails included in the file directory, where each task object respectively includes one or more mails. Here, by creating a task object, the task object can be processed based on the created thread to realize a search for a large-data-volume mail.

Subsequently, in step S250, each task object created in step S240 is processed with one or more threads in a thread pool, the threads being adapted to process each task object according to the search information. Here, each task object in the task queue is processed in turn by calling the thread pool by adding each task object created to the task queue.

It should be noted that, according to the technical solution of the present invention, when the total number of mails is greater than the first threshold and a search mechanism for a large data volume mail is adopted, a thread pool including one or more threads is created, and a task object including a plurality of mails is created for the mail under each file directory, so that the task object can be processed by using the threads, thereby improving the search efficiency of the mail, saving the time for the user to search the mail each time, and further enhancing the user experience.

Finally, in step S260, a search result list is generated according to the target mails in each task object, and the search result list is presented in the interface of the mailbox client, so that the user can view the target mails in the search result list. Here, the search result list includes information of a plurality of target mails, where each item in the search result list corresponds to one target mail information, respectively.

According to one embodiment, when one or more task objects are created according to a plurality of mails included in a file directory, the number of the mails included in the file directory is determined, the number of the task objects to be created is determined according to the number of the mails included in the file directory, and then the task objects with the corresponding number are created, and one or more mails in the file directory are respectively allocated to each task object.

Further, after the number of mails included in the file directory is determined, whether the number of mails is larger than a second threshold value is judged, if the number of mails in the file directory is larger than the second threshold value, the number of task objects to be created is determined according to the number of mails and the second threshold value, and after a corresponding number of task objects are created, a second threshold value number of mails are distributed to each task object. That is, when creating the task object, the task object is created according to the second threshold number of mails corresponding to each task object, so that when the number of mails in the file directory is greater than the second threshold, the number of the task objects to be created can be determined according to the ratio of the number of mails to the second threshold (when the ratio is a decimal number, the integer is added by 1), and then the second threshold number of mails are allocated to each task object. In addition, when the number of the mails left in the last distribution is less than the second threshold value, the mails left in the number less than the second threshold value are individually distributed to one task object.

If the mail address is not larger than the second threshold value, only one task object is created, and all mails under the file directory are allocated to the task object.

It should be noted that the present invention is not limited to the specific value of the second threshold. In one embodiment, the second threshold is 500, but the invention is not limited thereto.

According to one embodiment, in step S250, when processing each task object according to the search information, each task object is processed in turn by a thread, wherein for each task object, the content of each mail in the task object is checked in turn, and whether to take the mail as a target mail is determined by judging whether the search information is included in the content of each mail. Here, the content of the mail includes a subject of the mail, sender information, recipient information, a body of the mail, and the like, so that whether the mail is a target mail is determined by judging whether the subject of the mail, the sender information, the recipient information, the body of the mail include search information.

For each mail in the task object, if the content of the mail comprises search information, determining the mail as a target mail, and storing the target mail; and if the content of the mail does not comprise the search information, checking the next mail in the task object, judging whether the content of the next mail comprises the search information or not, and further determining whether the next mail is determined as the target mail or not. In this way, after each task object is processed according to the search information, the target mail in each task object can be acquired.

And if the search information is included in the mail content, determining the mail as the target mail. Otherwise, if the mail content does not include the search information, the content of the next mail is checked, and whether the next mail is the target mail is judged. And further, each determined target mail is obtained, a search result list is generated according to each determined target mail, and the search result list is displayed in an interface of the mailbox client, so that a user can view the target mails in the search result list. Here, the search result list includes information of a plurality of target mails, where each item in the search result list corresponds to one target mail information, respectively.

According to one embodiment, in step S230, by acquiring hardware information of the computing device 100, the number of threads to be created is determined according to the number of CPU cores (the number of CPU core unit groups) in the hardware information, and further, a corresponding number of threads are created. It should be noted that the present invention is not limited to the relationship between the number of CPU cores and the number of threads, for example, one core unit group may be set to correspond to one thread, or one core unit group may be set to correspond to two threads when the CPU of the current operating environment of the mailbox client supports the hyper-threading technology.

According to one embodiment, the number of threads in the created thread pool is represented as K, the number of CPU cores of the computing device 100 is represented as M, and the relationship between the number of CPU cores and the number of threads may be formulated as K = M/2 regardless of whether the CPU of the current runtime environment of the mailbox client supports the hyper-threading technology. In other words, the formula for determining the number of threads from the number of CPU cores is K = M/2, where K denotes the number of threads, M denotes the number of CPU cores, and the minimum value of K is 1. That is, the present invention handles mail searching by turning on half the number of CPU cores. Therefore, the invention can search the mails with large data volume by starting the thread under the condition of not influencing the system operation and the operation states of other application programs, thereby improving the mail searching efficiency, saving the time for searching the mails each time and avoiding the phenomenon of interface jamming.

In addition, according to an embodiment of the present invention, if it is determined in step S220 that the total number of mails in all file directories under the search directory is not greater than the first threshold, it is explained that it is not necessary to employ a search mechanism for a large-data-volume mail, in which case the mail is processed by performing the following method:

and traversing each mail under each file directory included in the search directory, checking the content of each mail, and judging whether the content of each mail comprises search information. Here, the content of the mail includes a subject of the mail, sender information, recipient information, a body of the mail, and the like, so that whether the mail is a target mail is determined by judging whether the subject of the mail, the sender information, the recipient information, the body of the mail include search information.

In summary, according to the mail search method of the present invention, for searching a large data volume mail, a thread pool including one or more threads is created, and a task object including a plurality of mails is created for the mail under each file directory, so that the task objects can be sequentially processed by using the threads, thereby improving the mail search efficiency when searching the large data volume mail, saving the time of searching the mail by the user each time, and further enhancing the user experience. And, the invention creates the thread used for processing the mail search based on half of the number of CPU cores, thus, when carrying on the mail search of the large data volume, can avoid the influence on system operation and other application program operating condition as far as possible.
