It also doesn't seem too difficult to implement on the UnifiedHighlighter, at least for someone who's familiar with the code.

> DefaultSolrHighlighter uses stored field content to highlight. It has some disadvantages, because index grows up fast when using multilingual indexing due to several fields has to be stored with same content. This patch allows DefaultSolrHighlighter to use "contentField" attribute to loockup content in external field.
> Excerpt from old schema:
> {code:xml}
> <field name="title" type="text" stored="true" indexed="true" />
> <field name="title_ru" type="text_ru" stored="true" indexed="true" />
> <field name="title_en" type="text_en" stored="true" indexed="true" />
> <field name="title_de" type="text_de" stored="true" indexed="true" />
> {code}
> The same after patching, highlighter will now get content stored in "title" field
> {code:xml}
> <field name="title" type="text" stored="true" indexed="true" />
> <field name="title_ru" type="text_ru" stored="false" indexed="true" contentField="title"/>
> <field name="title_en" type="text_en" stored="false" indexed="true" contentField="title"/>
> <field name="title_de" type="text_de" stored="false" indexed="true" contentField="title"/>
> {code}
