Linguistic search and sort
You can configure PolicyCenter to perform search and sort
operations in languages other than the default en_US. PolicyCenter provides support for language-appropriate text search and
sort for a single language.
Understanding linguistic search and sort of character data
There are two primary ways to search for and sort character data:
- Treat the character data as binary code points and compare and sort the data numerically.
- Treat the character data linguistically. This approach applies specific collation rules to order words in a list that reflect the commonly accepted practices and expectations for a particular language.
Linguistic search applies a specific collation to the character data. A collation is an overriding set of rules that applies to the ordering and comparison of the data. Collation strength refers to the elements of the collation process that the search and sort code applies to the data.
For example:
- Collation strength controls whether the search and sort code respects or ignores differences in case and accent on a character, such as the leading character on a word.
- In the Japanese language,
collation strength also controls whether the search and sort code respects
or ignores the differences between:
- Katakana and Hiragana
- Full-width and half-width Katakana character differences
PolicyCenter uses the value of configuration parameter DefaultApplicationLocale and the language_languageCode.xml and collations.xml configuration files to implement localized search and sort functionality.
