        """General purpose filter iterator.

        This general filter iterator allows the filtering of entries based
        on one or more custom filters. These filters must contain
        an entry of the `storage` attribute, a comparison operator, and the
        test value. For example, to filter out entries with coverage below 80::

            my_filter = ["coverage", ">=", 80]

        Filters should always be provide as a list of lists::

            iter_filter([["coverage", ">=", 80]])
            # or
            my_filters = [["coverage", ">=", 80],
                          ["identity", ">=", 50]]

            iter_filter(my_filters)

        As a convenience, a list of the desired databases can be directly
        specified using the `database` argument, which will only report
        entries for the specified databases::

            iter_filter(my_filters, databases=["plasmidfinder"])

        By default, this method will yield the complete entry record. However,
        the returned filters can be specified using the `fields` option::

            iter_filter(my_filters, fields=["reference", "coverage"])

        Parameters
        ----------
        filters : list
            List of lists with the custom filter. Each list should have three
            elements. (1) the key from the entry to be compared; (2) the
            comparison operator; (3) the test value. Example:
                ``[["identity", ">", 80]]``.
        databases : list
            List of databases that should be reported.
        fields : list
            List of fields from each individual entry that are yielded.
        filter_behavior : str
            options: ``'and'`` ``'or'``
            Sets the behaviour of the filters, if multiple filters have been
            provided. By default it is set to ``'and'``, which means that an
            entry has to pass all filters. It can be set to ``'or'``, in which
            case one one of the filters has to pass.
