OSID - osid.course.plan.PlanSearchSession Service Interface Definition

Interface	osid.course.plan.PlanSearchSession
Implements	`osid.course.plan.PlanQuerySession`
Used By	`osid.course.plan.CoursePlanManager`
Used By	`osid.course.plan.CoursePlanProxyManager`
Description	This session provides methods for searching `Plans`. The search query is constructed using the `PlanQuery`. The plan record `Type` also specifies the record for the plan query. `getPlansByQuery()` is the basic search method and returns a list of `CourseCatalog` elements. A more advanced search may be performed with `getPlansBySearch()`. It accepts a `PlanSearch` in addition to the query for the purpose of specifying additional options affecting the entire search, such as ordering. `getPlansBySearch()` returns a `PlanSearchResults` that can be used to access the resulting `PlanList` or be used to perform a search within the result set through `PlanSearch`. Plans may have a query record indicated by their respective record types. The query record is accessed via the `PlanQuery`. The returns in this session may not be cast directly to these interfaces.
