=head1 NAME
C4::Search::History - Manage search history
=head1 DESCRIPTION
This module provides some routines for the search history management.
It deals with session or database.
=head1 ROUTINES
=head2 add
C4::Search::History::add({
userid => $userid,
sessionid => $cgi->cookie("CGIESSID"),
query_desc => $query_desc,
query_cgi => $query_cgi,
total => $total,
type => $type,
});
type is "biblio" or "authority".
Add a new search to the user's history.
=head2 add_to_session
my $value = C4::Search::History::add_to_session({
cgi => $cgi,
query_desc => $query_desc,
query_cgi => $query_cgi,
total => $total,
type => $type,
});
Add a search to the session. The number of searches to keep is hardcoded to 15.
=head2 delete
C4::Search::History::delete({
userid => $loggedinuser,
sessionid => $sessionid,
type => $type,
previous => $previous
});
Delete searches in the database.
If the sessionid is missing all searches for all sessions will be deleted.
It is possible to delete searches for current session or all previous sessions using the previous flag.
If the type ("biblio" or "authority") is missing, all type will be deleted.
To delete *all* searches for a given userid, just pass a userid.
=head2 get
my $searches C4::Search::History::get({
userid => $userid,
sessionsid => $sessionid,
type => $type,
previous => $previous
});
Return a list of searches for a given userid.
If a sessionid is given, searches are limited to the matching session.
type and previous follow the same behavior as the delete routine.
=head2 get_from_session
my $searches = C4::Search::History::get_from_session({
cgi => $cgi
});
Return all searches present for the given session.
=head2 set_to_session
C4::Search::History::set_to_session({
cgi => $cgi,
search_history => $search_history
});
Store searches into the session.
