Date Tue, 07 Dec 2010 16:41:12 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1979?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12968813#action_12968813

Robert Muir commented on SOLR-1979:
-----------------------------------

bq. I have a plan to add profiles for the Norwegian and Sami languages when time allows: TIKA-491
TIKA-492

Did you plan to also upgrade tika from 639-1 for the Sami languages? the only 639-1 code i
see is "se" but this seems to be appropriate only for North Sami.

> 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.
