Problems solved by technology

[0002] At present, the existing map retrieval service products can only support a relatively single precise retrieval request
For the imprecise retrieval requirements of logical combinations of multiple conditions, for example, when the retrieval request for tourism data includes elements such as "area", "suitable crowd", and "distance limit", traditional map retrieval services cannot support

Abstract

The embodiment of the present invention proposes a map data retrieval method, device, retrieval server and system, wherein the method includes: parsing more than one retrieval condition from the map retrieval request; The retrieval method corresponding to the set of retrieved conditions parsed; when the corresponding retrieval method is the first retrieval method, use the above one or more retrieval conditions to generate a first retrieval request, send the first retrieval request, and the second retrieval method A retrieval method includes performing parallel retrieval by using more than one retrieved conditions parsed out and logically combining retrieval results; receiving retrieval results for the first retrieval request. The embodiment of the present invention can provide a search result corresponding to the first search mode in map data search.

Description

technical field [0001] The invention relates to the technical field of data retrieval, in particular to a map data retrieval method, device, retrieval server and system. Background technique [0002] At present, existing map retrieval service products can only support relatively single precise retrieval requests. Traditional map retrieval services cannot support the imprecise retrieval requirements of logical combinations of multiple conditions, such as when elements such as "area", "suitable crowd" and "distance limit" are included in the retrieval request for tourism data. Contents of the invention [0003] Embodiments of the present invention provide a map data retrieval method and device to at least solve the above technical problems in the prior art. [0004] In a first aspect, an embodiment of the present invention provides a map data retrieval method, including: [0005] Parse more than one retrieval condition from the map retrieval request; [0006] According to...
