  55 C4::Suggestions - Some useful functions for dealings with aqorders.
  56
  57 =head1 SYNOPSIS
  58
  59 use C4::Suggestions;
  60
  61 =head1 DESCRIPTION
  62
  63 The functions in this module deal with the aqorders in OPAC and in librarian interface
  64
  65 A suggestion is done in the OPAC. It has the status "ASKED"
  66
  67 When a librarian manages the suggestion, they can set the status to "REJECTED" or "ACCEPTED".
  68
  69 When the book is ordered, the suggestion status becomes "ORDERED"
  70
  71 When a book is ordered and arrived in the library, the status becomes "AVAILABLE"
  72
  73 All aqorders of a borrower can be seen by the borrower itself.
  74 Suggestions done by other borrowers can be seen when not "AVAILABLE"
  75
  76 =head1 FUNCTIONS

  78 =head2 SearchSuggestion
  79
  80 (\@array) = &SearchSuggestion($suggestionhashref_to_search)
  81
  82 searches for a suggestion
  83
  84 return :
  85 C<\@array> : the aqorders found. Array of hash.
  86 Note the status is stored twice :
  87 * in the status field
  88 * as parameter ( for example ASKED => 1, or REJECTED => 1) . This is for template & translation purposes.
