Joel Bernstein commented on SOLR-3897:
--------------------------------------
fragsize works only with the FastVectorHighlighter so if we want to ensure one
fragment per field value then we will have to work with the fragmenter. The
default fragmenter works in chunks of 100 characters.
At this point I'm thinking it might be best to leave it as it is. The user will
have to set the snippets count but this can be documented. Each field value
will be a single fragment unless the it has more then 100 characters and if
this an issue then a new fragmenter can be provided.

> Project: Solr
> Issue Type: Improvement
> Components: highlighter

> Assignee: Yonik Seeley

> The behavior of the default Solr hit highlighter on multi-value fields is to
> only return the values that have a hit and sort them by score.
> This ticket supplies a patch that adds a new highlight parameter called
> "preserveMulti" which can be used on a feild by field basis to return all of
> the values in their original order. If this parameter is used, the values
> that have a hit are highlighted and the ones that do not contain a hit are
> returned un-highlighted.
> The "preserveMulti" parameter works with the default standard highlighter and
> follows the standard highlighting conventions.
> Sample usage for a field called "cat":
> f.cat.hl.preserveMulti=true
