    Represents a field configuration.

    The FieldType object supports the following attributes:

    * format (formats.Format): the storage format for posting blocks.

    * analyzer (analysis.Analyzer): the analyzer to use to turn text into
      terms.

    * scorable (boolean): whether searches against this field may be scored.
      This controls whether the index stores per-document field lengths for
      this field.

    * stored (boolean): whether the content of this field is stored for each
      document. For example, in addition to indexing the title of a document,
      you usually want to store the title so it can be presented as part of
      the search results.

    * unique (boolean): whether this field's value is unique to each document.
      For example, 'path' or 'ID'. IndexWriter.update_document() will use
      fields marked as 'unique' to find the previous version of a document
      being updated.

    * multitoken_query is a string indicating what kind of query to use when
      a "word" in a user query parses into multiple tokens. The string is
      interpreted by the query parser. The strings understood by the default
      query parser are "first" (use first token only), "and" (join the tokens
      with an AND query), "or" (join the tokens with OR), "phrase" (join
      the tokens with a phrase query), and "default" (use the query parser's
      default join type).

    * vector (formats.Format or boolean): the format to use to store term
        vectors. If not a ``Format`` object, any true value means to use the
        index format as the term vector format. Any flase value means don't
        store term vectors for this field.

    The constructor for the base field type simply lets you supply your own
    attribute values.  Subclasses may configure some or all of this for you.

    Special field type that lets you index integer or floating point
    numbers in relatively short fixed-width terms. The field converts numbers
    to sortable bytes for you before indexing.

    You specify the numeric type of the field (``int`` or ``float``) when you
    create the ``NUMERIC`` object. The default is ``int``. For ``int``, you can
    specify a size in bits (``32`` or ``64``). For both ``int`` and ``float``
    you can specify a ``signed`` keyword argument (default is ``True``).

    >>> schema = Schema(path=STORED, position=NUMERIC(int, 64, signed=False))
    >>> ix = storage.create_index(schema)
    >>> with ix.writer() as w:
    ...     w.add_document(path="/a", position=5820402204)
    ...

    You can also use the NUMERIC field to store Decimal instances by specifying
    a type of ``int`` or ``long`` and the ``decimal_places`` keyword argument.
    This simply multiplies each number by ``(10 ** decimal_places)`` before
    storing it as an integer. Of course this may throw away decimal prcesision
    (by truncating, not rounding) and imposes the same maximum value limits as
    ``int``/``long``, but these may be acceptable for certain applications.

    >>> from decimal import Decimal
    >>> schema = Schema(path=STORED, position=NUMERIC(int, decimal_places=4))
    >>> ix = storage.create_index(schema)
    >>> with ix.writer() as w:
    ...     w.add_document(path="/a", position=Decimal("123.45")
    ...

        :param numtype: the type of numbers that can be stored in this field,
            either ``int``, ``float``. If you use ``Decimal``,
            use the ``decimal_places`` argument to control how many decimal
            places the field will store.
        :param bits: When ``numtype`` is ``int``, the number of bits to use to
            store the number: 8, 16, 32, or 64.
        :param stored: Whether the value of this field is stored with the
            document.
        :param unique: Whether the value of this field is unique per-document.
        :param decimal_places: specifies the number of decimal places to save
            when storing Decimal instances. If you set this, you will always
            get Decimal instances back from the field.
        :param shift_steps: The number of bits of precision to shift away at
            each tiered indexing level. Values should generally be 1-8. Lower
            values yield faster searches but take up more space. A value
            of `0` means no tiered indexing.
        :param signed: Whether the numbers stored in this field may be

    Special field type that lets you index datetime objects. The field
    converts the datetime objects to sortable text for you before indexing.

    Since this field is based on Python's datetime module it shares all the
    limitations of that module, such as the inability to represent dates before
    year 1 in the proleptic Gregorian calendar. However, since this field
    stores datetimes as an integer number of microseconds, it could easily
    represent a much wider range of dates if the Python datetime implementation
    ever supports them.

    >>> schema = Schema(path=STORED, date=DATETIME)
    >>> ix = storage.create_index(schema)
    >>> w = ix.writer()
    >>> w.add_document(path="/a", date=datetime.now())
    >>> w.commit()

            this argument, the field uses analysis.StandardAnalyzer.
        :param phrase: Whether the store positional information to allow phrase
            searching.
        :param chars: Whether to store character ranges along with positions.
            If this is True, "phrase" is also implied.
        :param stored: Whether to store the value of this field with the
            document. Since this field type generally contains a lot of text,
            you should avoid storing it with the document unless you need to,
            for example to allow fast excerpts in the search results.
        :param spelling: if True, and if the field's analyzer changes the form
            of term text (such as a stemming analyzer), this field will store
            extra information in a separate field (named using the
            ``spelling_prefix`` keyword argument) to allow spelling suggestions
            to use the unchanged word forms as spelling suggestions.
        :param sortable: If True, make this field sortable using the default
            column type. If you pass a :class:`whoosh.columns.Column` instance
            instead of True, the field will use the given column type.
        :param lang: automaticaly configure a
            :class:`whoosh.analysis.LanguageAnalyzer` for the given language.
            This is ignored if you also specify an ``analyzer``.
        :param vector: if this value evaluates to true, store a list of the
            terms in this field in each document. If the value is an instance
            of :class:`whoosh.formats.Format`, the index will use the object to
            store the term vector. Any other true value (e.g. ``vector=True``)
            will use the field's index format to store the term vector as well.

    Configured field that indexes text as N-grams. For example, with a field
    type NGRAM(3,4), the value "hello" will be indexed as tokens
    "hel", "hell", "ell", "ello", "llo". This field type chops the entire text
    into N-grams, including whitespace and punctuation. See :class:`NGRAMWORDS`
    for a field type that breaks the text into words first before chopping the
    words into N-grams.

    Represents the collection of fields in an index. Maps field names to
    FieldType objects which define the behavior of each field.

    Low-level parts of the index use field numbers instead of field names for
    compactness. This class has several methods for converting between the
    field name, field number, and field object itself.

        All keyword arguments to the constructor are treated as fieldname =
        fieldtype pairs. The fieldtype can be an instantiated FieldType object,
        or a FieldType sub-class (in which case the Schema will instantiate it
        with the default constructor before adding it).

        For example::

            s = Schema(content = TEXT,
                       title = TEXT(stored = True),

        deep copied, so they are shared between schema copies.

    Allows you to define a schema using declarative syntax, similar to
    Django models::

        class MySchema(SchemaClass):
            path = ID
            date = DATETIME
            content = TEXT

    You can use inheritance to share common fields between schemas::

        class Parent(SchemaClass):
            path = ID(stored=True)
            date = DATETIME

        class Child1(Parent):
            content = TEXT(positions=False)

        class Child2(Parent):
            tags = KEYWORD

    This class overrides ``__new__`` so instantiating your sub-class always
    results in an instance of ``Schema``.

    >>> class MySchema(SchemaClass):
    ...     title = TEXT(stored=True)
    ...     content = TEXT
    ...
    >>> s = MySchema()
    >>> type(s)
    <class 'whoosh.fields.Schema'>
