Abstract: A geographic information system engine system, an implementation method, a device and a storage medium thereof, which relate to the fields of intelligent search and cloud computing, are disclosed. The system may include: an underlying data source supporting N different data sources and a core engine layer, N being a positive integer greater than one; the core engine layer including a full-text search layer configured for serving as a cache for full-text search, implementing data consistency with the underlying data source through a distributed locking mechanism, and ensuring data timeliness by micro-batch updating; and a service providing layer configured for providing various services based on the full-text search layer and the underlying data source.
