I've used a separated core for storing suggestions, based on what I see in: https://github.com/cominvent/autocomplete. You can check the blog post on www.cominvent.com/2012/01/25/super-flexible-autocomplete-with-solr/. This is really flexible, on the downside it does not use the suggester component su this are like regular queries against a separated core.

For "Bill Rogers", index (untokenized) something like Bill|Bill Rogers Rogers|Bill Rogers Your suggester then is a simple term lookup (see TermsComponent) which is quite fast. What you _don't_ get is autocorrect. But if you use terms.prefix, you can also control whether it's whole word match or not. To get whole-word in the above, you would set your prefix to "Rogers|" for instance. Or you may want to leave off the "|" to see more of an autocomplete-type response. Then, of course, when you display this you need to only display what's after the "|" (or whatever delimiter you use). One other note, this will be case sensitive, so you probably want to do casing yourself, index things like rogers|Bill Rogers and lowercase what you send in to terms component.
