Subject [jira] Created: (SOLR-1979) Create LanguageIdentifierUpdateProcessor
Date Wed, 30 Jun 2010 20:35:52 GMT
Create LanguageIdentifierUpdateProcessor

                 Key: SOLR-1979
             Project: Solr
          Issue Type: New Feature
          Components: update
            Reporter: Jan Høydahl
            Priority: Minor

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|"]
in an UpdateProcessor. The processor should be configured like this:

  <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>
