best way to to get faster record searching in mysql

Question

I have a more than Billion records in mysql database , the problem is when I execute a select query it takes more than 3 minutes to search for that string.

So which is the best way to store and retrieve when I have large amount of data? My table has 4 columns:

 Serial_no,  product_name,  product_id,  location

The serial number is auto increment from 1. And I have duplicate product_id exits. I didn't performed any indexing, just created a table and querying using

select * from table where condition

So What Should I do If I want to have a faster query searching?

edit : I am using the below query :

select * from the table where product_name="Example";

Should I change my db to other db?

Answer 1

I would create the index according which is my most used fields in the where in my queries, in this case maybe your main field could be product_id so it should be the cluster index and create a non cluster index with the product_name

CREATE NONCLUSTERED INDEX [itable_productname] ON table 
(
    product_name ASC
)
