Accessing a canonical URL results in a search for 'python' in a standard set of books. Every time someone accesses this URL from Google search and every access from GoogleBot results in this search. Each search returns the exact same result.

Today, we go to ES for each of these requests. Instead, store it in memory (just like we store autocomplete and autocomplete2 settings) and do not go to ES if it is available in memory.

For now, we need to do this for the 6 books in production as future books will not have this issue because of ticket 1638.

Of course, when these books are updated, the "cache" should be deleted.
