It means you need to open an issue in that module's issue queue.

After I installed the module Document[1] in Drupal, I get a warning
message:

Warning: Parameter 1 to document_search_form() expected to be a
reference, value given
in retrieve_form() (line 772 of /var/www/intranet/includes/form.inc).

What this mean?
