It has the status "ASKED" When a librarian manages the suggestion, they can set the status to "REJECTED" or "ACCEPTED". When the book is ordered, the suggestion status becomes "ORDERED" When a book is ordered and arrived in the library, the status becomes "AVAILABLE" All aqorders of a borrower can be seen by the borrower itself. Suggestions done by other borrowers can be seen when not "AVAILABLE" =head1 FUNCTIONS =head2 SearchSuggestion (\@array) = &SearchSuggestion($suggestionhashref_to_search) searches for a suggestion return : C<\@array> : the aqorders found. Array of hash. Note the status is stored twice : * in the status field * as parameter ( for example ASKED => 1, or REJECTED => 1) .
