Sandia Reference

"This element marks the document as searchable -- the server on which the document is located must have a search engine defined that supports this searching. There are many older documents that have the ISINDEX declaration in the BODY. As a result, the HTML definition still allows this form. To the ISINDEX element we have added the PROMPT tag. ISINDEX indicates that a document is searchable index. PROMPT has been added so the document author can specify what message they want to appear before the text input field of the index. The default is of course that unfortunate message: 'this is a searchable index. Enter search keywords'" (I. Graham)

none= "Displays the following message followed by a textbox: 'You can search this index. Type the keyword(s) you want to search for;' When the user enters text and presses ENTER, that text is posted back to the page's URL as a query." (Microsoft)

Warning: there are two possible meanings of this particular use of "id=". There is the normal use of "id=" and follow the link on the attribute name for more information on that use.

The second meaning is used exclusively by WebTV. It is the same as the "name=" attribute below so the explanation is shared. Their description is as follows:

"The name attribute can be used with client functions. However, client functions are not recommended for content developers. These functions are intended for use by WebTV Networks for developing basic WebTV functionality."
