Shalin Shekhar Mangar commented on SOLR-1105:
---------------------------------------------

Instead of baking this into the schema, should this be turned on/off through a request parameter?

> 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}
