The analysis-extras plugin provides additional analyzers that rely
upon large dependencies/dictionaries.

It includes integration with ICU for multilingual support,
analyzers for Chinese and Polish, and integration with
OpenNLP for multilingual tokenization, part-of-speech tagging
lemmatization, phrase chunking, and named-entity recognition.
