I need to set the index.mapping.attachment.indexed\_chars value to the maximum possible but I wasn't able to understand how should I set such value.ù Can someone explain me how to set it using Java API ? Tks Tullio ---

You can set it to -1 to have no limit. You can set the mentioned setting either when you create the index through the Java API in the settings, or in the node configuration file.
