Indexing Service in Microsoft Windows XP uses Component Object Model (COM) objects and interfaces available through the Mlang APIs to provide support for 150 locales.
CiLocale can be specified in the .idq or .ida file. It can also be specified by the browser as the HTTP_ACCEPT_LANGUAGE variable. Values entered in the .idq and .ida files supersede those sent in HTTP_ACCEPT_LANGUAGE. If no value is found in the .idq or .ida file, the value of HTTP_ACCEPT_LANGUAGE is read from left to right to find a supported language.
For example:
HTTP_ACCEPT_LANGUAGE=EN, FR, CZ
Note
Values are separated by commas.
