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

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