Mike Klaas commented on SOLR-516:
---------------------------------
A quite reasonable addition, thanks!. I commited the core patch but named the
parameter hl.maxAlternateFieldLength. Since it is so long anyway, it doesn't
hurt to be explicit.
I have zero familiarity with the ruby side of Solr, so I will leave the issue
open for the ruby client patch to be reviewed and applied.
> Add hl.alternateFieldLen parameter, to set max length for hl.alternateField

> Project: Solr

> 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.
