    TermRangeTermsEnum(TermsEnum, BytesRef, BytesRef, Boolean, Boolean)

    Enumerates all terms greater/equal than lowerTerm but less/equal than upperTerm.

    If an endpoint is null, it is said to be "open". Either or both endpoints may be open. Open endpoints may not be exclusive (you can't select all but the first or last term without explicitly specifying the term to exclude.)

    Declaration
    public TermRangeTermsEnum(TermsEnum tenum, BytesRef lowerTerm, BytesRef upperTerm, bool includeLower, bool includeUpper)
    Parameters
    Type Name Description
    TermsEnum tenum

    TermsEnum to filter

    BytesRef lowerTerm

    The term text at the lower end of the range

    BytesRef upperTerm

    The term text at the upper end of the range

    System.Boolean includeLower

    If true, the lowerTerm is included in the range.

    System.Boolean includeUpper

    If true, the upperTerm is included in the range.
