Michael McCandless commented on LUCENE-6061:
--------------------------------------------
PH is able to highlight arbitrary fields, even if that field did not in fact
participate in the query. It just extracts all terms from the query, and then
loads the fields you asked for, finding all locations where those terms occur
in those fields. You can see it running at

> Add Support for something different than Strings in Highlighting
> (FastVectorHighlighter)
> ----------------------------------------------------------------------------------------

> Key: LUCENE-6061
> URL: https://issues.apache.org/jira/browse/LUCENE-6061
> Project: Lucene - Core
> Issue Type: Wish
> Components: core/search, modules/highlighter
> Affects Versions: Trunk
> Reporter: Martin Braun
> Priority: Critical
> Labels: FastVectorHighlighter, Highlighter, Highlighting
> Fix For: 4.10.2, 5.0, Trunk
>
>
> In my application I need Highlighting and I stumbled upon the really neat
> FastVectorHighlighter. One problem appeared though. It lacks a way to render
> the Highlights into something different than Strings, so I rearranged some of
> the code to support that:
> https://github.com/Hotware/LuceneBeanExtension/blob/master/src/main/java/de/hotware/lucene/extension/highlight/FVHighlighterUtil.java
> Is there a specific reason to only support String[] as a return type? If not,
> I would be happy to write a new class that supports rendering into a generic
> Type and rewire that into the existing class (or just do it as an addition
> and leave the current class be).
