Title: search parameters overrideable

Code is a little bit convoluted (owing to the fact that search config is not just a flat object), but the end effect is that passing in a third parameter of e.g.

```
{
highlight: true,
facets: {
minThreshold: 50,
names: ["regions']
}
}
```
will override as you'd expect it to.

In addition if the key `names` was replaced with `'+names'` then the array woudl be concatenated with the default list of names.

If this looks good I'll write tests and document properly
