HTML Question

What is the <isindex> element in HTML?

Apparently after doing a little research on the HTML

<head>
element I learned of the semi-existence of the
<isindex>
element and how it seems to have never been fully implemented... I believe. What was the intention behind this element and why was it deprecated?

Answer

From the MDN reference:

<isindex> is an obsolete HTML element that puts a text field in a page for querying the document. <isindex> was providing a single line text input for entering a query string. When sent, the server would return a list of pages matching the query. It supports depended on both the browser and the server to react to the query.

<isindex> is deprecated as of HTML 4.01, because the same behaviour can be achieved with an HTML form.
