-- | Creates a value of 'ListConfigurations' with the minimum fields required to make a request.

-- Use one of the following lenses to modify other fields as desired:
--
-- * 'lcOrderBy' - Certain filter criteria return output that can be sorted in ascending or descending order. For a list of output characteristics for each filter, see <http://docs.aws.amazon.com/application-discovery/latest/APIReference/discovery-api-queries.html#ListConfigurations Using the ListConfigurations Action> .
--
-- * 'lcFilters' - You can filter the request using various logical operators and a /key/ -/value/ format. For example:  @{"key": "serverType", "value": "webServer"}@  For a complete list of filter options and guidance about using them with this action, see <http://docs.aws.amazon.com/application-discovery/latest/APIReference/discovery-api-queries.html#ListConfigurations Querying Discovered Configuration Items> .
--
-- * 'lcNextToken' - Token to retrieve the next set of results. For example, if a previous call to ListConfigurations returned 100 items, but you set @ListConfigurationsRequest$maxResults@ to 10, you received a set of 10 results along with a token. Use that token in this query to get the next set of 10.
--
-- * 'lcMaxResults' - The total number of items to return. The maximum value is 100.
--
-- * 'lcConfigurationType' - A valid configuration identified by Application Discovery Service.
