HTML <isindex> element is utilized to create a one-line text input on a webpage for querying a document. When a user submits input to the server, the server responds with a list of pages that match the query.
The <isindex> element is versatile and can be inserted at any point in the content, although it is recommended to place it within the <head> element whenever possible.
Note: Do not use <isindex> tag as it is not supported by HTML5, instead of it you can use form <input> which will do the same work.
