The analysis-extras plugin provides additional analyzers that rely
|
||||
upon large dependencies/dictionaries.
|
||||
|
||||
It includes integration with ICU for multilingual support, and
|
||||
analyzers for Chinese and Polish.
|
||||
|
||||
Relies upon the following lucene components (in lucene-libs/):
|
||||
|
||||
* lucene-analyzers-icu-X.Y.jar
|
||||
* lucene-analyzers-smartcn-X.Y.jar
|
||||
* lucene-analyzers-stempel-X.Y.jar
|
||||
|
||||
And the ICU library (in lib/):
|
||||
|
||||
* icu4j-X.Y.jar
