public class ICUCollationKeyFilterFactory
extends TokenFilterFactory
implements MultiTermAwareComponent, ResourceLoaderAware

Factory for ICUCollationKeyFilter.

This factory can be created in two ways:

• Based upon a system collator associated with a Locale.
• Based upon a tailored ruleset.

Using a System collator:

• locale: RFC 3066 locale ID (mandatory)
• strength: 'primary','secondary','tertiary', 'quaternary', or 'identical' (optional)
• decomposition: 'no', or 'canonical' (optional)

Using a Tailored ruleset:

• custom: UTF-8 text file containing rules supported by RuleBasedCollator (mandatory)
• strength: 'primary','secondary','tertiary', 'quaternary', or 'identical' (optional)
• decomposition: 'no' or 'canonical' (optional)

Expert options:

• alternate: 'shifted' or 'non-ignorable'. Can be used to ignore punctuation/whitespace.
• caseLevel: 'true' or 'false'. Useful with strength=primary to ignore accents but not case.
• caseFirst: 'lower' or 'upper'. Useful to control which is sorted first when case is not ignored.
• numeric: 'true' or 'false'. Digits are sorted according to numeric value, e.g. foobar-9 sorts before foobar-10
• variableTop: single character or contraction. Controls what is variable for 'alternate'
