TikaLanguageIdentifierUpdateProcessorFactory (Solr 9.0.0 langid API)

java.lang.Object
- org.apache.solr.update.processor.UpdateRequestProcessorFactory
- - org.apache.solr.update.processor.TikaLanguageIdentifierUpdateProcessorFactory

All Implemented Interfaces:

LangIdParams, NamedListInitializedPlugin, SolrCoreAware
```
public class TikaLanguageIdentifierUpdateProcessorFactory
extends UpdateRequestProcessorFactory
implements SolrCoreAware, LangIdParams
```
Identifies the language of a set of input fields using Tika's LanguageIdentifier. The tika-core-x.y.jar must be on the classpath
The UpdateProcessorChain config entry can take a number of parameters which may also be passed as HTTP parameters on the update request and override the defaults. Here is the simplest processor config possible:
```
 <processor class="org.apache.solr.update.processor.TikaLanguageIdentifierUpdateProcessorFactory">
   <str name="langid.fl">title,text</str>
   <str name="langid.langField">language_s</str>
 </processor>
 
```
