OSID - osid.subscription.DispatchSearchSession Service Interface Definition

Interface	osid.subscription.DispatchSearchSession
Implements	`osid.subscription.DispatchQuerySession`
Used By	`osid.subscription.SubscriptionManager`
Used By	`osid.subscription.SubscriptionProxyManager`
Description	This session provides methods for searching `Dispatches`. The search query is constructed using the `DispatchQuery`. The dispatch record `Type` also specifies the record for the dispatch query. `getDispatchesByQuery()` is the basic search method and returns a list of `Dispatch` elements. A more advanced search may be performed with `getDispatchesBySearch()`. It accepts a `DispatchSearch` in addition to the query for the purpose of specifying additional options affecting the entire search, such as ordering. `getDispatchesBySearch()` returns a `DispatchSearchResults` that can be used to access the resulting `DispatchList` or be used to perform a search within the result set through `DispatchSearch`. Dispatches may have a query record indicated by their respective record types. The query record is accessed via the `DispatchQuery`. The returns in this session may not be cast directly to these interfaces.
