=head1 NAME
C4::Accounts - Functions for dealing with Koha authorities
=head1 SYNOPSIS
use C4::Suggestions;
=head1 DESCRIPTION
The functions in this module deal with the suggestions :
* in OPAC
* in librarian interface
A suggestion is done in the OPAC. It has the status "ASKED"
When a librarian manages the suggestion, he can set the status to "REJECTED" or "ORDERED".
When a book is ordered and arrived in the library, the status becomes "AVAILABLE"
All suggestions of a borrower by the borrower itself.
Suggestions done by other can be seen when not "AVAILABLE"

=item SearchSuggestion
(\@array) = &SearchSuggestion($user)
searches for a suggestion
C<$user> is the user code (used as suggestor filter)
return :
C<\@array> : the suggestions found. Array of hash.
Note the status is stored twice :
* in the status field
* as parameter ( for example ASKED => 1, or REJECTED => 1) . This is for template & translation purposes.
