A simle search engine

A simple search engine We are asked to write a program in Visual C++ that implements search a string supplied by a user. You will be provided several text files in the share folder. The aim of your program is to choose the file or files among these that best matches the search string supplied by the user. As the measure of the match we will use the number of occurences of the wordds making up the search string in the text file. Your program should ask the user to enter a search string that he wants to use for the search. The search string can be in one of the following formats: 1. keyword: just a single word. The best match in this case is the file with the largest occurance of this keyword. 2. keyword1 keyword2 keyword3: multiple keywords seperated by space. A text file matches these set of keywords if it contains all of these keywords. 3. "keyword1 keyword2" a phrase . the matching file contains the complete phrase the largest number of times. The user will be given four options: 1. see sample lines from another file in the list of mathcing files. 2. refine the search by entering an additional search string. 3. start a new search 4. quit. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform windows XP, Windows 2000 language: C++ (visual C++ is preferred)
