Description

Is it possible to highlight documents in the "expand" section in the Solr response?

I'm aware that https://cwiki.apache.org/confluence/x/jiBqAg states:
"All downstream components (faceting, highlighting, etc...) will work with the collapsed result set."

So I tried to put the highlight component after the expand component like this:

<arr name="components">
	<str>query</str>
	<str>facet</str>
	<str>stats</str>
	<str>debug</str>
	<str>expand</str>
	<str>highlight</str>
</arr>

But with no effect.

Is there another switch that needs to be flipped or could this be implemented easily?
IMHO this is quite a common use case. And it was possible to highlight all results of a group with the old grouping.
