HTML | <isindex> tag

The <isindex> tag is used to querying any document through a text field. Means this tag inform the browser that the user wants to provide the search function through the document. If you want to search any specific word in a long article this tag is helpful then. But during these days all the browsers contain that feature by pressing CTRL + F will let you search the word, so this tag is no more useful these days.


<isindex promt="search">


  • prompt: This attribute contains a string which is label for the text field.
  • action: This attribute holds the URL when you need to send the query to a different URL.

Note: HTML5 does not support <isindex> tag.





<!Doctype html>
    <title>HTML isindex Tag</title>
    <isindex prompt="Search" />
        h1 {
            color: green;
        <h2>HTML <isindex> tag</h2>
