Want your fields to autocomplete, but an instance field is either too broad or too narrow? Use a live search to populate your Dynamic Options field.

Options pull up nodes based on a pre-defined list or the results of a search node. For example, if you want to autocomplete an "Author" field to all #people or #companies, you could write a live search for that into that field configuration.

You can also create live searches that narrow down your options. An instance field would let you autocomplete to all #books. Say you want only unread #books with a rating higher than 4 as options in this particular field – dynamic options lets you do that.
