> USE CASE:
> You have a document that is composed of (short) title and (long) body fields and want body to be highlighted.
> In order to avoid highlighted body field to be empty, you can use hl.alternateField parameter.
> Although you want to set f.body.hl.alternateField=body, you may set f.body.hl.alternateField=title,
> because response time is awful when the body values are big. But the title field provides users with
> information smaller than body field.
> In this case, you can use f.body.hl.alternateFieldLen=100 to limit the body length to 100 characters.
