HTML <isindex> Tag
The HTML <isindex> tag is not supported in HTML5. To query a document by providing a single-line text input in a page, the HTML <isindex> tag was used earlier. The list of the pages that matched with the query, was sent by the server in return. This tag was preferably placed within the <head> tag. The HTML form <input> tag is used nowadays to serve the same purpose.
Syntax:
<isindex prompt = text />
Example:
<!DOCTYPE html> <html> <head> <isindex prompt = "Hello World!!" /> </head> </html>
Tag-specific Attributes:

| action | URL | To send the query to various URLs (and not the current document). |
