 CAVEAT: C<search_literal> is provided for Class::DBI compatibility and should
-only be used in that context. There are known problems using C<search_literal>
-in chained queries; it can result in bind values in the wrong order.  See
-L<DBIx::Class::Manual::Cookbook/Searching> and
+only be used in that context. C<search_literal> is a convenience method. 
+It is equivalent to calling $schema->search(\[]), but if you want to ensure
+columns are bound correctly, use C<search>.
+
+Example of how to use C<search> instead of C<search_literal>
+
+  my @cds = $cd_rs->search_literal('cdid = ? AND (artist = ? OR artist = ?)', (2, 1, 2));
+  my @cds = $cd_rs->search(\[ 'cdid = ? AND (artist = ? OR artist = ?)', [ 'cdid', 2 ], [ 'artist', 1 ], [ 'artist', 2 ] ]);
+
+
+See L<DBIx::Class::Manual::Cookbook/Searching> and 
 L<DBIx::Class::Manual::FAQ/Searching> for searching techniques that do not
 require C<search_literal>.
