            Parameters:
                title (str, optional): General string query to search for. Partial string matches are allowed.
                sort (:class:`~plexapi.library.FilteringSort` or str or list, optional): A field to sort the results.

            Raises:
                :exc:`~plexapi.exceptions.BadRequest`: When the sort or filter is invalid.
                :exc:`~plexapi.exceptions.NotFound`: When applying an unknown sort or filter.

            **Sorting Results**

            The search results can be sorted by including the ``sort`` parameter.

            * See :func:`~plexapi.library.LibrarySection.listSorts` to get a list of available sort fields.

            The ``sort`` parameter can be a :class:`~plexapi.library.FilteringSort` object or a sort string in the
            format ``field:dir``. The sort direction ``dir`` can be ``asc``, ``desc``, or ``nullsLast``. Omitting the
            sort direction or using a :class:`~plexapi.library.FilteringSort` object will sort the results in the default
            direction of the field. Multi-sorting on multiple fields can be achieved by using a comma separated list of
            sort strings, or a list of :class:`~plexapi.library.FilteringSort` object or strings.

            Examples:

                .. code-block:: python

                    library.search(sort="titleSort:desc")  # Sort title in descending order
                    library.search(sort="titleSort")  # Sort title in the default order
                    # Multi-sort by year in descending order, then by audience rating in descending order
                    library.search(sort="year:desc,audienceRating:desc")
                    library.search(sort=["year:desc", "audienceRating:desc"])

            **Using Plex Filters**

            Any of the available custom filters can be applied to the search results
            (`screenshot <../_static/images/LibrarySection.search.png>`__).

            * See :func:`~plexapi.library.LibrarySection.listFields` to get a list of all available fields.
            * See :func:`~plexapi.library.LibrarySection.listOperators` to get a list of all available operators.
            * See :func:`~plexapi.library.LibrarySection.listFilterChoices` to get a list of all available filter values.

            The following filter fields are just some examples of the possible filters. The list is not exaustive,
            and not all filters apply to all library types.

            * **actor** (:class:`~plexapi.media.MediaTag`): Search for the name of an actor.
            * **addedAt** (*datetime*): Search for items added before or after a date. See operators below.

            * **unwatched** (*bool*): Search for unwatched items.
            * **userRating** (*int*): Search for items with a specific user rating.
            * **writer** (:class:`~plexapi.media.MediaTag`): Search for the name of a writer.
            * **year** (*int*): Search for a specific year.

            Tag type filter values can be a :class:`~plexapi.library.FilterChoice` object,
            :class:`~plexapi.media.MediaTag` object, the exact name :attr:`MediaTag.tag` (*str*),
            or the exact id :attr:`MediaTag.id` (*int*).
            
            Date type filter values can be a ``datetime`` object, a relative date using a one of the
            available date suffixes (e.g. ``30d``) (*str*), or a date in ``YYYY-MM-DD`` (*str*) format.

            Relative date suffixes:

            * ``s``: ``seconds``
            * ``m``: ``minutes``
            * ``h``: ``hours``
            * ``d``: ``days``
            * ``w``: ``weeks``
            * ``mon``: ``months``
            * ``y``: ``years``
            
            Multiple values can be ``OR`` together by providing a list of values.

            Examples:

                .. code-block:: python

                    library.search(unwatched=True, year=2020, resolution="4k")
                    library.search(actor="Arnold Schwarzenegger", decade=1990)
                    library.search(contentRating="TV-G", genre="animation")
                    library.search(genre=["animation", "comedy"])  # Genre is animation OR comedy
                    library.search(studio=["Disney", "Pixar"])  # Studio contains Disney OR Pixar

            **Using a** ``libtype`` **Prefix**

            Some filters may be prefixed by the ``libtype`` separated by a ``.`` (e.g. ``show.collection``,
            ``episode.title``, ``artist.style``, ``album.genre``, ``track.userRating``, etc.). This should not be
            confused with the ``libtype`` parameter. If no ``libtype`` prefix is provided, then the default library
            type is assumed. For example, in a TV show library ``viewCout`` is assumed to be ``show.viewCount``.
            If you want to filter using episode view count then you must specify ``episode.viewCount`` explicitly.
            In addition, if the filter does not exist for the default library type it will fallback to the most
            specific ``libtype`` available. For example, ``show.unwatched`` does not exists so it will fallback to
            ``episode.unwatched``. The ``libtype`` prefix cannot be included directly in the function parameters so
            the filters must be provided as a filters dictionary.

            Examples:

                .. code-block:: python

                    library.search(filters={"show.collection": "Documentary", "episode.inProgress": True})
                    library.search(filters={"artist.genre": "pop", "album.decade": 2000})

                    # The following three options are identical and will return Episode objects
                    showLibrary.search(title="Winter is Coming", libtype='episode')
                    showLibrary.search(libtype='episode', filters={"episode.title": "Winter is Coming"})
                    showLibrary.searchEpisodes(title="Winter is Coming")

                    # The following will search for the episode title but return Show objects
                    showLibrary.search(filters={"episode.title": "Winter is Coming"})

                    # The following will fallback to episode.unwatched
                    showLibrary.search(unwatched=True)

            **Using Plex Operators**

            Operators can be appended to the filter field to narrow down results with more granularity. If no
            operator is specified, the default operator is assumed to be ``=``. The following is a list of
            possible operators depending on the data type of the filter being applied. A special ``&`` operator
            can also be used to ``AND`` together a list of values.

            Type: :class:`~plexapi.media.MediaTag` or *subtitleLanguage* or *audioLanguage*

            * ``=``: ``is``
            * ``!=``: ``is not``

            Type: *int*

            * ``=``: ``is``
            * ``!=``: ``is not``
            * ``>>=``: ``is greater than``
            * ``<<=``: ``is less than``

            Type: *str*

            * ``=``: ``contains``
            * ``!=``: ``does not contain``
            * ``==``: ``is``
            * ``!==``: ``is not``
            * ``<=``: ``begins with``
            * ``>=``: ``ends with``

            Type: *bool*

            * ``=``: ``is true``
            * ``!=``: ``is false``

            Type: *datetime*

            * ``<<=``: ``is before``
            * ``>>=``: ``is after``

            Type: *resolution*

            * ``=``: ``is``

            Operators cannot be included directly in the function parameters so the filters
            must be provided as a filters dictionary. The trailing ``=`` on the operator may be excluded.

            Examples:

                .. code-block:: python

                    # Genre is horror AND thriller
                    library.search(filters={"genre&": ["horror", "thriller"]})

                    # Director is not Steven Spielberg
                    library.search(filters={"director!": "Steven Spielberg"})

                    # Title starts with Marvel and added before 2021-01-01
                    library.search(filters={"title<": "Marvel", "addedAt<<": "2021-01-01"})

                    # Added in the last 30 days using relative dates
                    library.search(filters={"addedAt>>": "30d"})

                    # Collection is James Bond and user rating is greater than 8
                    library.search(filters={"collection": "James Bond", "userRating>>": 8})

            **Using Advanced Filters**

            Any of the Plex filters described above can be combined into a single ``filters`` dictionary that mimics
            the advanced filters used in Plex Web with a tree of ``and``/``or`` branches. Each level of the tree must
            start with ``and`` (Match all of the following) or ``or`` (Match any of the following) as the dictionary
            key, and a list of dictionaries with the desired filters as the dictionary value.

            The following example matches `this <../_static/images/LibrarySection.search_filters.png>`__ advanced filter
            in Plex Web.

            Examples:

                .. code-block:: python

                    advancedFilters = {
                        'and': [                            # Match all of the following in this list
                            {
                                'or': [                     # Match any of the following in this list
                                    {'title': 'elephant'},
                                    {'title': 'bunny'}
                                ]
                            },
                            {'year>>': 1990},
                            {'unwatched': True}
                        ]
                    }
                    library.search(filters=advancedFilters)

            **Using PlexAPI Operators**

            For even more advanced filtering which cannot be achieved in Plex, the PlexAPI operators can be applied
            to any XML attribute. See :func:`plexapi.base.PlexObject.fetchItems` for a list of operators and how they
            are used. Note that using the Plex filters above will be faster since the filters are applied by the Plex
            server before the results are returned to PlexAPI. Using the PlexAPI operators requires the Plex server
            to return *all* results to allow PlexAPI to do the filtering. The Plex filters and the PlexAPI operators
            can be used in conjunction with each other.

            Examples:

                .. code-block:: python

                    library.search(summary__icontains="Christmas")
                    library.search(duration__gt=7200000)
                    library.search(audienceRating__lte=6.0, audienceRatingImage__startswith="rottentomatoes://")
                    library.search(media__videoCodec__exact="h265")
