If you set `NGram` for Japanese, you can use SentenceBreakingOptions for normalization.

Default: | `0` (off)
Required: | No
Configuration Section: | LanguageTypes or `MyLanguage`
Example: | `Encodings=UTF8:JapaneseUTF8 NGram=2` In this example, all text is indexed as N-grams of two characters.

NOTE: If you change this setting after you have indexed content into IDOL Server, the new setting applies only to new content, and the server logs a warning. To clear the warning and ensure that your change applies to all your content, you must initialize your index and reindex the content.
