OSID - osid.ordering.ProductSearchSession Service Interface Definition

Interface	osid.ordering.ProductSearchSession
Implements	`osid.ordering.ProductQuerySession`
Description	This session provides methods for searching `Product` objects. The search query is constructed using the `ProductQuery.` The product record `Type` also specifies the record for the product query. `getProductsByQuery()` is the basic search method and returns a list of `Product` elements. A more advanced search may be performed with `getProductsBySearch().` It accepts a `ProductSearch` in addition to the query for the purpose of specifying additional options affecting the entire search, such as ordering. `getProductsBySearch()` returns a `ProductSearchResults` that can be used to access the resulting `ProductList` or be used to perform a search within the result set through `ProductSearch.` Products may have a query record indicated by their respective record types. The query record is accessed via the `ProductQuery.` The returns in this session may not be cast directly to these interfaces.
