Modifier and Type	Field	Description
static final List<String>	LUCENE_UNICODE_WHITESPACES
static final List<String>	OS_UNICODE_WHITESPACES
static final Pattern	PATTERN_REMOVE_PUNCTUATION	Pre-compiled pattern for REGEX_REMOVE_PUNCTUATION for better performance(?) Using this pattern instead of compiling the regex each time should improve performance.
static final String	REGEX_REMOVE_PUNCTUATION	This regex is hideous, but is faster than the simpler one This regex captures all characters between the first non-whitespace/non-punctuation character and the last non-whitespace/non-punctuation character For example, " CONFSRVDEV-XYZ123!" will be captured as "CONFSRVDEV-XYZ123", it also works with unicode characters such as Japanese symbols The exact search index will store both the original token "CONFSRVDEV-XYZ123!" and the captured token "CONFSRVDEV-XYZ123", so exact searches will work with both
