What is IDQ (Internet Data Query)?

Internet Data Query is a text file with the extension .idq that defines the basic parameters for a Microsoft Index Server query. These parameters include the scope of the query and its restrictions (the words being searched for). The Internet Data Query (IDQ) file is the handler for the Hypertext Markup Language (HTML) query form used to issue the query. The result set generated by the IDQ file is formatted into HTML using an HTML Extension (HTX) file (.htx file) and returned to the user.

Developing a query or search page for a Web site that can use Index Server involves creating three files:

  • The HTML form that presents the search page to the user
  • The IDQ form handler that executes the query
  • The HTX file that formats the results returned to the user

Internet Data Query is deprecated

Indexing Service is no longer supported as of Windows XP and is unavailable for use as of Windows 8. Instead, use Windows Search for client-side search and Microsoft Search Server Express for server-side search.

TIP

Although you can use Active Server Pages (ASP) scripting to issue and format Index Server queries, IDQ/HTX files offer better performance.
