Embodiment Construction
[0060] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0061]In the process of users searching for Poi, users have relatively clear geographical requirements. One of the core ideas of the embodiment of the present invention is: after the inverted index of Poi is created, the inverted index of Poi is divided into blocks according to the city to which Poi belongs to obtain city-based index blocks; thus, in the subsequent search process, you can Search in the index block according to the city of the Poi to be searched, that is, narrow the search range, thereby improving the search efficiency.
[0062] refer to figure 1 , which shows a flow chart of the steps of an embodiment of the method for establishing an index library according to the present invention, which may specifically includ...

The embodiment of the present invention provides an index database construction method, a search method and a device. Wherein, the method for constructing the index library includes: scanning the data source of the point of interest Poi to determine the attribute information and city information of each Poi; creating an inverted index of Poi according to the attribute information of each Poi; Segment the inverted index to obtain index blocks based on city information; build a Poi index library based on the index blocks. The embodiment of the present invention builds the Poi index library based on the index blocks of the city, and realizes the purpose of storing the Poi according to the city to which the Poi belongs, so that in the subsequent search process, it can be carried out according to the corresponding index block of the city to which the Poi belongs in the Poi index library Search narrows down the search scope and improves search efficiency.
Description
technical field [0001] The present invention relates to the field of search technology, in particular to an index library construction method, an index library-based search method, an index library construction device, an index library-based search device, a device and a readable storage medium. Background technique [0002] With the rapid development of the mobile Internet, more and more users use the network to obtain services, such as information network services based on Point of Interest (Poi). Poi refers to data that people are interested in, such as restaurants, scenic spots, schools and other buildings, or road information such as Beijing-Tibet Expressway, etc. [0003] At present, more and more users use mobile terminals to search Poi on the map. Specifically, the existing Poi search solution usually determines the corresponding Poi name according to the query word input by the user, and searches for the corresponding Poi results at different locations on the map ...
