BitmapColumnIndex	forRange(String startValue, boolean startStrict, String endValue, boolean endStrict, com.google.common.base.Predicate<String> matcher) Get a BitmapColumnIndex corresponding to the values supplied in the specified range whose dictionary ids also match some predicate, such as to match a prefix.

                                  boolean endStrict)

Description copied from interface: LexicographicalRangeIndex

Get a BitmapColumnIndex corresponding to the values supplied in the specified range. If supplied starting value is null, the range will begin at the first non-null value in the underlying value dictionary. If the end value is null, the range will extend to the last value in the underlying value dictionary.

Description copied from interface: LexicographicalRangeIndex

Get a BitmapColumnIndex corresponding to the values supplied in the specified range whose dictionary ids also match some predicate, such as to match a prefix. If supplied starting value is null, the range will begin at the first non-null value in the underlying value dictionary that matches the predicate. If the end value is null, the range will extend to the last value in the underlying value dictionary that matches the predicate. If the provided matcher is always true, it's better to use the other LexicographicalRangeIndex.forRange(String, boolean, String, boolean) method.
