OSID - osid.search.EngineSearchSession Service Interface Definition

Interface	osid.search.EngineSearchSession
Implements	`osid.search.EngineQuerySession`
Used By	`osid.search.SearchManager`
Used By	`osid.search.SearchProxyManager`
Description	This session provides methods for searching `Engines`. The search query is constructed using the `EngineQuery`. The engine record `Type` also specifies the record for the engine query. `getEnginesByQuery()` is the basic search method and returns a list of `Engine` elements. A more advanced search may be performed with `getEnginesBySearch()`. It accepts an `EngineSearch` in addition to the query for the purpose of specifying additional options affecting the entire search, such as ordering. `getEnginesBySearch()` returns an `EngineSearchResults` that can be used to access the resulting `EngineList` or be used to perform a search within the result set through `EngineSearch`. Engines may have a query record indicated by their respective record types. The query record is accessed via the `EngineQuery`. The returns in this session may not be cast directly to these interfaces.
