If your field "all" is of type "text", indexing and searching would go through the analyzers (tokenizers and filters) specified ONLY for the text field. It does not matter if data from a "edgytext" or any other field type is being copied into the field.
Having said that converting the "all" field to type "edgytext" should still work fine. All your regular searches on a text field should also work with the edgytext field. Ain't it like that?
