The invention provides a method for searching for stores by means of database indexes. According to the method, a Web server, a position service cluster, a database server and a plurality of mobile clients need to be provided. The method includes the steps that firstly, position data of all the stores are processed in advance, the data indexes are built according to the sequence of longitudes and latitudes and are stored in a database of the database server; secondly, the mobile clients send requests, the WEB server receives request data of the mobile clients and is responsible for forwarding requests for searching for information of nearby stores to the service cluster; thirdly, the position service cluster processes the requests in a distributed mode, data of the stores in the longitude and latitude range are obtained through the indexing function of the database server, and result sets are quickly returned to the mobile clients. By means of the method, processing results can be returned to front-end users in a short time after the requests are received, and the nearby stores can be quickly searched for.
