  75 C4::Suggestions - Some useful functions for dealings with aqorders.
  76
  77 =head1 SYNOPSIS
  78
  79 use C4::Suggestions;
  80
  81 =head1 DESCRIPTION
  82
  83 The functions in this module deal with the aqorders in OPAC and in librarian interface
  84
  85 A suggestion is done in the OPAC. It has the status "ASKED"
  86
  87 When a librarian manages the suggestion, he can set the status to "REJECTED" or "ACCEPTED".
  88
  89 When the book is ordered, the suggestion status becomes "ORDERED"
  90
  91 When a book is ordered and arrived in the library, the status becomes "AVAILABLE"
  92
  93 All aqorders of a borrower can be seen by the borrower itself.
  94 Suggestions done by other borrowers can be seen when not "AVAILABLE"
  95
  96 =head1 FUNCTIONS
  97
  98 =head2 SearchSuggestion
  99

 101
 102 searches for a suggestion
 103
 104 return :
 105 C<\@array> : the aqorders found. Array of hash.
 106 Note the status is stored twice :
 107 * in the status field
 108 * as parameter ( for example ASKED => 1, or REJECTED => 1) . This is for template & translation purposes.
