OSID - osid.metering.UtilitySearchSession Service Interface Definition

Interface	osid.metering.UtilitySearchSession
Implements	`osid.metering.UtilityQuerySession`
Used By	`osid.metering.MeteringManager`
Used By	`osid.metering.MeteringProxyManager`
Description	This session provides methods for searching `Utility` objects. The search query is constructed using the `UtilityQuery`. The utility record `Type` also specifies the recod for the utility query. `getUtilitiesByQuery()` is the basic search method and returns a list of `Utility` elements. A more advanced search may be performed with `getUtilitiesBySearch()`.It accepts a `UtilitySearch` in addition to the query for the purpose of specifying additional options affecting the entire search, such as ordering. `getUtilitiesBySearch()` returns a `UtilitySearchResults` that can be used to access the resulting `UtilityList` or be used to perform a search within the result set through `UtilitySearch`. Utilities may have a query record indicated by their respective record types. The query record is accessed via the `UtilityQuery`. The returns in this session may not be cast directly to these interfaces.
