Abstract

The invention provides an index sequencing updating method and device, relates to the field of calculation technology and search, and aims at solving the problems that the state of an information releaser and other real-time updating factors cannot be reflected to the search result timely and thus the search result is inaccurate in the prior art. The method comprises the steps of performing reversed-sequencing index calculation for a data segment to obtain a first sequencing result according to the first search request; storing the first sequencing result into a cache; performing regular-sequencing index calculation for the first sequencing result in the cache according to the real-time updated releaser state in order to update the first sequencing result on real time.

Description

technical field [0001] The invention relates to the field of computing and information technology, in particular to an information display method and device. Background technique [0002] The ranking of information in the search results of classified information websites is affected by many factors, in addition to the relevance of the information itself, update time and other factors, there are also the status of the information publisher, the category and location of the information, and so on. [0003] However, in the prior art, when factors such as the status of the publisher change, due to the large amount of data and high real-time requirements, it is difficult for the system to reflect these factors in the information ranking of the search results in a timely manner, thus making the search results inaccurate. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an index sorting and updating method and device to ...
