HTML <isindex> tag
Updated: 11/13/2018 by Computer Hope
When writing in HTML (hypertext markup language), the <isindex> tag was used to designate a single-line text box for entering a query string. It was used to allow servers to send search results based on the characters in submitted string. The following sections contain information about this tag, including an example of its code, and related attributes and browser compatibility.
Example of <isindex> code
<head> <isindex prompt="What would you like to search?" />
