Solr don't index pages created in pt_BR locale (Brazilian Portuguese)

Without dynamicfield "*_BR" Solr indexing don't index pages created in pt_BR (Brazilian Portugues).

To test, I changed "%XWIKI_DATADIR%\solr\xwiki\conf\schema.xml":

<dynamicField name="*_BR"  type="text_pt"    indexed="true"  stored="true" multiValued="true" />

After reindex, the search works.

Initially analyzer 'text_pt' Portuguese bit for Brazilian Stopwords.
