Index.mapping.attachment.indexed_chars how to set

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 ?

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.
