Abstract

The embodiment of the invention discloses a method and device for extracting contents of index pages and a search engine. The method comprises the following steps: extracting the contents of a current index page in a index page series of a specified website and comparing a subject link set in the current index page with a historical subject link set extracted last time; because responding to the fact that the subject link set in the current index page does not have intersection with the historical subject link set, positioning a next index page to carry out content extraction. The network resource embodying and coverage rates of Spider can be increased under the condition that the flow cost is not increased by adopting the embodiment of the invention.

Description

technical field [0001] The invention relates to Internet technology, in particular to a method and device for extracting index page content, and a search engine. Background technique [0002] HTML (HypertextMarkupLanguage, Hypertext Markup Language) documents as Internet resources are connected using hyperlinks, just like weaving a web. Search engines use spiders (web crawlers, also known as web spiders) to find web resources. Spider is located at the most upstream of the search engine data stream, and is responsible for collecting resources on Internet sites into local databases for subsequent retrieval. It is one of the most important data sources for search engines. The goal of Spider is to discover and crawl all valuable web pages on the Internet. [0003] At present, most Internet sites organize website resources in the form of index pages and page turning. When new resources are added, old resources are moved backward or forward to the page turning series. For spide...
