9. Use of AND/OR Be careful of duplicated search result Each product should be displayed only once in the search result Duplicated product will deduct marks

10.

12. Improvement 1.Use frame to implement the search engine (0.5 marks) –The upper frame for the user input –The lower frame for displaying the search result 2.Multiple key word search (1.5 marks) − Each word in the ‘text’ field should be processed as individual word. − Combine the search result using OR

13. How to match a word/string in another string? Use Regular expressions (RegExp) E.g. var key1 = ‘Snoopy’; var key2 = ‘Mcmug’; var data = ‘Hello Kitty and Snoopy’; var reg1 = RegExp(key1); var reg2 = RegExp(key2); var result1 = data.match(reg1); Var result2 = data.match(reg2);

14. Suggestion in Implementation Use Array to store the data of each product. The Array should be a Global variable Only simple details of each product are required To implement multiple key word search, you may use split()
