Sir, I have built an application where a user types a long string as input. Then after he/she types a single word of that string. I'm supposed to show all strings which have that word in them. Ex. the string typed in is "With regards to the correction in pay" later on in the search module the user types the keyword "pay". I'm just not able to solve this problem. Please provide me with the necessary coding. I'm using servlet and JSP(ajax) on the frontend and oracle at the backend.
