------------------------------------
bq. Why did you add a boolean flag for this to FieldProperties with the related
modification to SchemaField accordingly?
Answering my own question... I could imagine that it's useful metadata for a
non-stored field to declare that some other field is the source of it's
indexed/analyzed text. But the schema already internally tracks copyField
source/destination data. Maybe what we could do is have highlighting
automatically work on a non-stored field when we see that the field to be
highlighted is a copyField target? Then, in practice, most users wouldn't even
need to specify hl.contentField (though as an explicit option, it's still nice).

> Project: Solr
> Issue Type: Improvement
> Components: highlighter
> Reporter: Dmitry Lihachev
> Assignee: David Smiley
> Attachments: SOLR-1105-1_4_1.patch, SOLR-1105.patch,

> 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}
