I have an index which (among others) contains the following fields:

- title
- authors
- suggest

I'm copying the _title_ and the _authors_ fields into _suggest_ with copy\_to.  
Now I've noticed that I do not get suggestions when I type in the last name  
of an author - which makes sense because the completion suggester is a  
prefix suggester. However, I'd like to extend it to also work with last  
names in this example.

As I see it, there are two options:

1. Index _Stephenie Meyer_ as both _Stephenie Meyer_ and just _Meyer_ in  
the _suggest_ field.
2. Not use a suggester but instead use a search for completion, as  
described here  
[http://blog.qbox.io/multi-field-partial-word-autocomplete-in-elasticsearch-using-ngrams](http://blog.qbox.io/multi-field-partial-word-autocomplete-in-elasticsearch-using-ngrams)  
.

It seems to me that the first option is preferable since it makes use of  
FSTs and is therefore much faster. However, how can I make Elasticsearch  
copy the _title_ and _authors_ field into _suggest_ accordingly? Or is this  
only possible by manually creating the suggest field myself (instead of  
using an Elasticsearch feature like copy\_to)?
