Google Search Appliance: Search Protocol Reference Request Format 32
Automatic Language Filters
The Google Search Appliance automatically detects the language of each search query and returns
results in that language. For example, if a user submits a search query in Hungarian (lang_hu), results
are automatically returned in Hungarian.
The algorithm for automatically determining the language of a web document is not customizable. The
language of a document is determined primarily by the language used for the majority of the text in the
body of the document.
Note: Encoding schemes for the input and output of search requests are also important when you
provide international search. For more information on encoding, see “Internationalization” on page 34.
For more information on how language filtering works with Simplified Chinese and Traditional Chinese,
see “Language Filtering for Traditional and Simplified Chinese” on page 33.
