This is the same as putting quotes around all of the words entered. The searches are not case sensitive. The Advanced Search page gives you the ability to further refine the Simple Search query Language Limits results to only those pages containing the chosen language. Given the number of multi-lingual phrases available in standard speech and documents, some text from other languages is quite possible on the same page, but the predominant page text should clearly be from the specific language chosen. For FAST Search to correctly interpret and display searches for a specific language, it is important that you also select a character set that matches your browser settings and support the characters of the selected language.
Some languages have more than one matching character set.
Use the pulldown menu to select the proper one if needed. The customize page has more examples for the different character sets. Whenever you select a new character set from the pulldown menu, the page will be reloaded and encoded for that character set, so that your input can be correctly interpreted. To do this, you will need a program for writing Chinese characters along with the proper Chinese fonts. The program you are using will produce characters in a certain character set, for example BIG5, a character set for Traditional Chinese.
