Problems solved by technology

The string fuzzy query in Oracle usually uses the method like "%keyword%" to retrieve. Since this method cannot use the index, each fuzzy match will scan the entire table, not only the retrieval speed is slow, but also consumes a lot of system CPU, and thus affect the normal use of other modules in the application
Moreover, in this way, when there is a combination search of multiple keywords, the efficiency is lower

Embodiment Construction

[0075] like figure 2 Said, it is a kind of address matching method of the present invention, comprising:

[0076] Step 11, obtain the query word input by the user; for example, the user input: "Qinqinjiayuan, Hangzhou".

[0077] Step 12, splitting the query word into at least one index keyword; for example, splitting "Hangzhou Qinqinjiayuan" input by the user into "Hangzhou City" and "Qinqinjiayuan".

[0078] Step 13, according to the pre-established correspondence between index keywords and address information, obtain the address information corresponding to each of the index keywords; assume that there are the following three address information;

[0079] 1 Room 601, Building 14, Yaojiang Wending Garden, Xihu District, Hangzhou 2 Unit 1, Building 14, Qinqin Homeland, Sandun Town, Xihu District, Hangzhou 3 Room 601, Unit 1, Building 1, Lantian City Garden, Tiancheng Road, Xiacheng District, Hangzhou

[0080] The corresponding relationship between...

Abstract

The invention provides an address matching method and device. The address matching method includes acquiring a query term inputted by the user; dividing the query term into at least one index keyword; according to corresponding relation of preset index keywords and address information, acquiring address information corresponding to the index keywords one to one; displaying at least one of the address information. The address matching method and device allow higher searching speed.

Description

technical field [0001] The invention relates to the field of retrieval, in particular to a method and device for address matching. Background technique [0002] With the rapid development of fixed network services, higher requirements are placed on system support capabilities. In the face of massive address data, how to achieve efficient and fast positioning when handling front-end business is a new issue that needs to be faced. Traditional mobile services (such as mobile phones) communicate through wireless technology, and the location of the terminal is not fixed, so there is no need to care about the location attribute of the terminal when handling. However, due to its "linearity", fixed-line services are bound by linearity, and users must be in the area covered by mobile to handle corresponding services. Therefore, when the front-end business is handled, it is very important to confirm whether the user's installation address has been covered. [0003] This importance ...
