Martin Braun commented on LUCENE-6061:
--------------------------------------
Well I am doing the synonym approach for other parts already, but I think the
FastVectorHighlighter approach is better as it does exactly the part with "when
I highlight field X, load its content from field Y", but I just want it to be
able to render into arbitrary objects (or in my case I just want the plain
offsets).
I am currently working on a more sophisticated approach that lets me search for
more information about one single token (I am reindexing the document's tokens
into a new index) and that let's me do the highlighting as well so I am not
that dependent on the Highlighting API anymore.
Generally I just want to make the Highlighter API (I am talking about
_FastVectorHighlighter_ here) easier to use and more intuitive than what I
would need to do with the indexing trick.

> 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).
