It's really just a matter of what you're intentions are. There are an awful lot of highlighting params and so highlighting is very flexible and customizable. Regarding snippets, as an example Google presents two snippets in results, which is fairly common. I'd recommend doing a lot of experimenting by changing the params on the query string to get what you want, and then setting them up in SolrJ. The example I sent was intended to be a generic starting point and mostly just to show how to set highlighting params and how to get back a List of highlighting results.
