David Smiley commented on SOLR-1105:
------------------------------------
I propose separating this issue into a Lucene portion and Solr portion. I have
some thoughts on the Lucene side but I'll save it for later when you post that.
I like the "hl.contentField" param name. You declared it in
{{HighlightParams}} in a spot that I think should be down in the "misc"
category (pretty minor).
Why did you add a boolean flag for this to FieldProperties with the related
modification to SchemaField accordingly?

> Project: Solr
> Issue Type: Improvement
> Components: highlighter
> Reporter: Dmitry Lihachev
> Assignee: David Smiley

> 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}
