-----------------------------------

The idField input parameter is just used for decent logging if detection fa=
ils. It would be more elegant to get the id field name automatically throug=
h SolrCore...

> We need the ability to detect language of some random text in order to ac=
t 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 c=
ontent.
> To do this, we wrap the Tika LanguageIdentifier in an UpdateProcessor. Th=
e processor is configurable like this:
> {code:xml}=20
>   <processor class=3D"org.apache.solr.update.processor.LanguageIdentifier=
UpdateProcessorFactory">
>     <str name=3D"inputFields">name,subject</str>
>     <str name=3D"outputField">language_s</str>
>     <str name=3D"idField">id</str>
>     <str name=3D"fallback">en</str>
>   </processor>
> {code}=20
> It will then read the text from inputFields name and subject, perform lan=
guage identification and output the ISO code for the detected language in t=
he outputField. If no language was detected, fallback language is used.
