Embodiment Construction

[0053] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0054] figure 1 It is a system topology diagram according to one aspect of the present invention, showing a system in which a first node and a second node in a peer-to-peer network cooperate to implement indexing. Wherein, the system includes a plurality of first nodes 10 and a plurality of second nodes 20 connected thereto via a network. Specifically, one first node 10 may be connected to multiple second nodes 20 via a network, and the second node 20 obtains a first-level resource crawling task, and performs resource crawling according to the first-level resource crawling task, To establish a second index corresponding to the first-level resource crawling task, and send the second index to the corresponding at least one first node 10; correspondingly, the corresponding first node 10 receives from at least one first node 10 Two nodes 20 send at least one se...

Abstract

The invention aims to providing a method, device and system for establishing index in the peer-to-peer network. The second node gets the crawling task of the first level resource; has resource crawling according to the crawling task resource of the first level resource, and establishes the second index corresponding to the first level resource crawling task; and sends the second index to at least a first node. The first node receives at least a second index from at least a second node; selects at least a second index to establish the first index corresponding to the second index. The invention of the web search method, device and system is characterized by effective resolving the problems of traditional Internet search technology, such as low searching efficiency caused by server performance and / or network bandwidth limitation. In addition, the invention can also improve the search efficiency of resources in peer-to-peer network.

Description

technical field [0001] The invention relates to the technical field of network search, in particular to a technology for establishing an index in a peer-to-peer network. Background technique [0002] At present, the amount of various information on the Internet is growing explosively. Traditionally, when an Internet user needs to obtain a specific resource in the vast network resources, it is only possible to achieve the goal by searching a large number of resources in the network through a search server. [0003] In the traditional client / server networking mode, users search for network resources through a search server, and the search server provides users with corresponding search results according to the index established by it. In the process, the index is one of the key factors affecting the user's search experience. The establishment of an index is limited by the processing performance of the search server on the one hand, that is, the search server needs to have hi...
