What this article will cover?
In this tutorial I’ll illustrate how to implement the multiple keyword search technique. The focus is on searching one or more keywords or even full sentence or long text specified by a user in search text box.
1. Setup MySql Table
To implement this tutorial you require a MySql Table. In this example I have created a very simple Table named 'table1' with only one Field named 'field1'.
2. Create HTML Form
The next step is to create HTML form. The HTML Form, in this tutorial, is very simple form. It has a label, a text box (also called INPUT box), and a search button. This form allows user to type one or more keywords in the text box and search those values by clicking search button. The form will look like following:
4. Build the Logic
This is the next step after creating user interface (UI) and specifying connection setting to MySql. The logic which I have implemented is given in code below:
5. Display the Result
The result is displayed as HTML table in which the first column shows the serial number for rows and second column displays the data fetched from the matching rows in the 'field1'.

Done!
Now it works. Try different words, variations, editing code, experiment. I'm adding full code of both files in case you think you've missed something. Feel free to ask questions or ask for tutorials.
