I have a website in which I want to add a functionality of searching. I have created the website using ASP.NET and the data is stored in Apache hive. In the search functionality, I want to create a feature wherein the user must get suggestions based on data from database.

There is at least 50 columns in the database and the user could be searching data from any of the columns. I want my search function to recognize what the user is typing and suggest accordingly. I have no function to know which column the user is searching from, it is to be done from the server side. I don't want to use python as it would be slower.

So any suggestions for what I can do using JavaScript?
