Overview

Holds all media returned by each method relying on Fotolia::Base#search.

Acts like an Array as all missing methods are passed to the instance variable @media which is an Array in fact.

Fotolia::Base#search doesn’t return an Array but a SearchResultSet insteaad, because Fotolia’s API restricts the number of media returned per search query to a maximum of 64. The SearchResultSet allows you to easily fetch all media – the results are parted in pages.

You may access these pages by calling pages on the SearchResultSet. The pages are held in an Fotolia::SearchResultSet::Pages object.
