Subject [jira] Updated: (SOLR-1979) Create LanguageIdentifierUpdateProcessor
Date Wed, 30 Jun 2010 20:37:50 GMT

     [ https://issues.apache.org/jira/browse/SOLR-1979?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jan Høydahl updated SOLR-1979:
------------------------------

    Description: 
We need the ability to detect language of some random text in order to act upon it, such as
indexing the content into language aware fields. Another usecase is to be able to filter/facet
on language on random unstructured content.

To do this, we should wrap the [Nutch LanguageIdentifier|http://nutch.apache.org/apidocs-1.1/org/apache/nutch/analysis/lang/LanguageIdentifier.html"]
in an UpdateProcessor. The processor should be configured like this:

{code:xml} 
  <processor class="org.apache.solr.update.processor.LanguageIdentifierUpdateProcessorFactory">
    <str name="inputFields">title,teaser,body</str>
    <str name="isoOutputField">language</str>
    <str name="fullOutputField">language_display</str>
  </processor>  
{code}
