No - we'll have localised versions of the text field as well, and
appropriate copyField directives for each language, along the lines of:

<fieldType "text_en" class="solr.TextField" ...>
  <analyzer>
    ...
    <filter class="solr.EnglishMinimalStemFilterFactory/>
  </analyzer>
</fieldType>

<fieldType "text_es" class="solr.TextField" ...>
  <analyzer>
    ...
    <filter class="solr.SpanishLightStemFilterFactory"/>
  </analyzer>
</fieldType>

<field name="title_en" type="text_en" .../>
<field name="title_es" type="text_es" .../>
<field name="description_en" type="text_en" .../>
<field name="description_es" type="text_es" .../>
<field name="text_en" type="text_en" multiValued="true" .../>
<field name="text_es" type="text_es" multiValued="true" .../>

<copyField source="title_en" dest="text_en"/>
<copyField source="description_en" dest="text_en"/>
<copyField source="title_es" dest="text_es"/>
<copyField source="description_es" dest="text_es"/>

A request to /api/v1/search?q=foo with a header "Accept-Language: es"
would cause the Index to query Solr with "?q=text_es:foo".

Thoughts?
