(session, model, search_params)
return query
Performs the search specified by the given parameters on the model
    specified in the constructor of this class.

    This function essentially calls :func:`create_query` to create a query
    which matches the set of all instances of ``model`` which meet the search
    parameters defined in ``search_params``, then returns all results (or just
    one if ``search_params['single'] == True``).

    This function returns a single instance of the model matching the search
    parameters if ``search_params['single']`` is ``True``, or a list of all
    such instances otherwise. If ``search_params['single']`` is ``True``, then
    this method will raise :exc:`sqlalchemy.orm.exc.NoResultFound` if no
    results are found and :exc:`sqlalchemy.orm.exc.MultipleResultsFound` if
    multiple results are found.

    `model` is a SQLAlchemy declarative model class representing the database
    model to query.

    `search_params` is a dictionary containing all available search
    parameters. For more information on available search parameters, see
    :ref:`search`. Implementation note: this dictionary will be converted to a
    :class:`SearchParameters` object when the :func:`create_query` function is
    called.
