Product Info General
A Search engine is a tool for locating information on the Internet. A basic search engine consists of two parts, a Robot part/program and a Search part/program. Implementation: It establishes connection with the remote server, sends a package of data via a standard HTTP request, and then waits for a response. Once response is received, the data collected is stored in a temporary file and connection with server is closed. Control is then transferred to an Active Server Page(ASP), which performs certain operations on the data received from the remote server and stores it in another file. through a simple HTML form. The Search program is an Active Server Page. After it receives its input, it proceeds to open the file containing all the indexed HTML documents (websites). It, then, starts browsing through the Keywords for each individual web page and in the event that a match is found, the ASP includes the URL for that document in the output that is being written out to the user. And with that, the execution of the program comes to an end.

.The Robot
A robot is a software packet that helps implement the functionality of a search engine. A robot has three main properties. When given an HTML document as an input it: a.retrieves the document, b.indexes the document according to certain, programmer defined criteria, c.and stores it in a database of some type.
structure consists of two parts. A Socket based C++ program is the main part. It is essentially a client-side application, implemented via Sockets(Sockets are software devices used for communication between remote locations via a standard protocol, in this case a client and a server via the TCP/IP protocol).
.The Search
The Search program takes as an input the information that a user is searching for in the form of a string, usually about 2-3 words long. This input is being forwarded to the search program
