Problems solved by technology

However, if the POI information search system returns all search results to the search request based on category words, the complexity of its processing is increased; moreover, the search based on category words is often accompanied by high-frequency change views (such as dragging the map view Or changing the zoom level of the electronic map) not only increases the data processing burden of the map search server, but also affects the response time to other search requests, reducing the processing performance of the map search server

Abstract

The invention discloses a POI information search method, device and system and related equipment. The method includes the steps that a class search request is received, wherein the class search request carries class terms and at least one map block identifier; each class term is combined with each map block identifier; for each combination, a POI information set corresponding to the combination is searched for in a pre-stored POI information table, wherein the POI information set includes POI information, corresponding to the class term, in a POI included in a map block corresponding to the map block identifier in the combination; the POI sets corresponding to the combinations are fed back. By means of the method, the processing burden of a map search server can be alleviated, and the processing performance of the map search server can be improved.

Description

technical field [0001] The present invention relates to the technical field of data search, in particular to a POI information search method, device, system and related equipment. Background technique [0002] In the Internet-based POI information search, the search based on category words has become one of the popular search methods. Classifiers refer to words representing the categories of POIs (Point of Interest), such as searching for "restaurants" and "hotels" in electronic maps. In the existing map search server, when searching for POIs based on search keywords, usually only a preset number of search results are returned, for example, the top 10 most relevant search results are returned. [0003] In the search based on category words, users usually hope to get all POI information within the scope of the electronic map view. For example, when searching for "hotel", they hope to display all hotel POIs on the electronic map, so that they can search according to their own...
