In embodiments of the present invention, described map electronic search method at least comprises the steps.
S101, obtains at least two keywords of user's input.
In embodiments of the present invention, after user inputs keyword in the client being provided with electronic chart application, this keyword is transferred to described electronic chart searcher by network.Now, described electronic chart searcher is namely by keyword that network reception user inputs.
In embodiments of the present invention, user may need to search for the region with multiple point of interest sometimes, such as user wants to find a region simultaneously having XX bank and XX hotel, now, user inputs keyword " XX hotel of XX bank " in the electronic chart application of client, wherein, separate, as separated with space or comma with the separator preset in the middle of these two keywords.Be understandable that, in other embodiments of the invention, user also can input the keyword of 3 keywords, 4 keywords or more in described electronic chart application simultaneously, and the present invention is not specifically limited.
S102, obtains interest point set one to one according to keyword from index in map information database; Wherein, comprise all points of interest arrived according to described keyword index in described interest point set, described point of interest is the map element matched with described keyword in described map information database.
In embodiments of the present invention, described electronic chart searcher is after at least two keywords obtaining user's input, described electronic chart searcher obtains the point of interest corresponding with described keyword and described point of interest according to described keyword from index in map information database, wherein, all map element of described electronic chart can be comprised, place name, street name or building name etc. that all coordinate points on described map element and described electronic chart are corresponding in described map information database.The process of point of interest described in index can be that the map element (as place name, street name or build name) of preserving in the keyword that utilizes user to input and described map information database carries out text matches, and the map element keyword that map element and user input being met predetermined matching degree (if matching degree is more than 80%, or other matching algorithms) is defined as described point of interest.
In embodiments of the present invention, the described point of interest indexed, after indexing described point of interest, according to described keyword, is positioned in interest point set by described electronic chart searcher.Be specially, suppose that the keyword that described user inputs comprises the first keyword, the second keyword ... N keyword, then all points of interest obtained according to described first keyword index are positioned in the first interest point set by described electronic chart searcher, the all points of interest obtained according to described second keyword index are positioned in the second interest point set ..., all points of interest obtained according to described N keyword index are positioned in N interest point set.
S103, is respectively each interest point set and configures different indicateing arms, can be presented in the electronic chart application of client to make the point of interest in each interest point set with the form of the indicateing arm be configured.
In embodiments of the present invention, point of interest corresponding to different keywords can be distinguished in described electronic chart application to make user, described electronic chart searcher also configures different indicateing arms to different interest point set, as configured at least mark of difform indicateing arm or different colours to different interest point set, or configure at least mark of difformity and different colours simultaneously.Such as, indicateing arm that can be red to the first interest point set configuration, the indicateing arm green to the second interest point set configuration, the indicateing arm etc. blue to the 3rd interest point set configuration, or, indicateing arm that can be circular to the first interest point set configuration, configures square indicateing arm to the second interest point set, configures leg-of-mutton indicateing arm etc. to the 3rd interest point set.
In embodiments of the present invention, described electronic chart searcher is after configuring described indicateing arm to described interest point set, described interest point set is sent to the electronic chart application being positioned at client, described electronic chart application receives described interest point set, and after resolving the indicateing arm that each interest point set and each interest point set be configured, with the form of the indicateing arm of correspondence, the point of interest in described interest point set is all presented on the interface of described electronic chart, and on described interface, shows the corresponding relation of indicateing arm and keyword simultaneously.
The electronic chart searching method that the embodiment of the present invention provides, by carrying out index to the different keywords inputted simultaneously, and different indicateing arms is configured to the interest point set that different keyword obtains, thus user is when performing index while multi-key word, can distinguish and obtain interest point set by different keyword index, make user can by the map needed for different indicateing arm fast searchings and area information, Consumer's Experience be good.
