> 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 wrap the Tika LanguageIdentifier in an UpdateProcessor. The 
> processor is configurable like this:
> {code:xml} 
>   <processor 
> class="org.apache.solr.update.processor.LanguageIdentifierUpdateProcessorFactory">
>     <str name="inputFields">name,subject</str>
>     <str name="outputField">language_s</str>
>     <str name="idField">id</str>
>     <str name="fallback">en</str>
>   </processor>
> {code} 
> It will then read the text from inputFields name and subject, perform 
> language identification and output the ISO code for the detected language in 
> the outputField. If no language was detected, fallback language is used.
