Search machine for Internet information and System for Internet information searching having search machine, and Method for searching information on the Internet}

The present invention relates to an Internet searcher, and more particularly, a user's search for a search result of an Internet information, and a URL (Uniform Resource Locator) command input unit of a browser (generally, users understand a URL command input unit of a browser as an Internet address input unit. The present invention relates to an internet searcher capable of providing an internet information search result for a search term to a browser, an internet information search system having the same, and an internet information search method.

Existing methods for internet information retrieval are to perform a web information retrieval by entering a search term into a search term input unit provided by the website by executing a browser that is a HTTP client and providing an internet information retrieval service. will be. In such an existing Internet information retrieval system and information retrieval method, there is an inconvenience that a user must first visit a website that provides an Internet information retrieval server.

In the Internet searcher disclosed in the present invention, the Internet information search system and the Internet information search method including the same, a user inputs a search word to search for Internet information on a URL command input unit provided in a browser, and performs Internet information search. Internet information retrieval is possible without visiting a website that provides a search service.

Conventional methods related to this are to use a special browser or to install a special program that works with a general browser in advance. A method of providing is provided.

Therefore, there is no way for users to search for Internet information by inputting a search word for Internet information search in the URL command input unit of the web browser without installing an additional program using a general web browser.

1 is a diagram illustrating a typical network of an information delivery system according to an existing Internet environment. FIG. 2 is a flowchart illustrating a process of a browser processing an HTTP request to a user's web server in an Internet environment.

The information delivery system according to the existing Internet environment, as shown in Figure 1, the internal network 20, the router 30 and the Internet network 40 to retrieve information desired by the browser (client) 10 Through the web server 60 is configured to obtain the desired information. At this time, in the Internet network according to the TCP / IP (Transmission Control Protocol / Internet Protocol) protocol, the browser 10 is a 4-byte IP address of the web server 60 (currently, if the IP address is based on IPv4, the IP address is a 4-byte address scheme. It is composed of four numbers from 0 to 255 and separated by dots. For example, 143.248.151.111 becomes an IP address.

The general way for a user to make an HTTP request to a web server is to input a command according to the URL (Uniform Resource Locator) system, which is a standard for indicating the location of various information on the Internet, in the URL command input section of a browser. The system is configured in the form of "computer name / directory name / file name with protocol: // information".

In the Internet network according to the TCP / IP protocol, every computer has an IP address of 4 bytes to indicate its location, and the communication on the Internet is performed by identifying the logical location of each other through the IP address. However, since the user knows the IP address of the web server in advance, it is inconvenient for the user to use the IP address of the web server for the URL command request, and the domain name system (DNS) has been devised to alleviate this inconvenience.

In DNS, computer names on the Internet are represented by a string of alphanumeric characters separated by periods, instead of an IP address represented by a four-byte number. This is called a domain name. For example, the domain name representing "Korea Cheong Wa Dae" is "www.president.go.kr". However, domain names are a way for users to easily identify computers on the Internet, and to communicate between computers, you need to know the IP addresses assigned to each computer. Provided for this is a DNS server 50. The DNS server 50 is a server that provides a service for resolving domain names into numeric IP addresses.

Based on the above description, the process of performing the HTTP request to the website 60 by the browser 10 will be described with reference to FIG. 2 as follows.

The browser 10 receives the URL request of the website 50 to be accessed from the user (S10), and determines whether the server name of the web server 60 indicated in the URL is an IP address (S20). When the name of the input web server 60 is not an IP address, the browser 10 sends the IP address of the web server 60 corresponding to the name of the web server 60 input in the URL to the DNS server 50. Request (S30) and receives the IP address of the web server 60 from the DNS server (S50) (S40). The browser 10 performs a URL request to the web server 60 based on the IP address of the web server 60 (S50) and displays the result received from the web server 60 in the browser (S60).

If the user wants to search for Internet information corresponding to a certain search word on the Internet, the user has to inconvenience first to visit a website that provides an Internet information search service. In order to solve this problem, there have been suggested methods to search the Internet information by inputting the search word that the user wants to search the Internet information into the URL command input part of the browser. You must use the program.

Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art, the user inputs a search word that the user wants to search the Internet information without the installation of additional programs using a general browser to the Internet browser URL command input unit The purpose of the present invention is to provide an internet searcher, an internet information search system having the same, and an internet information search method.
