LuceneTextAnalyzerTransformer

class LuceneTextAnalyzerTransformer extends HasInputColsTransformer with Logging with MLWritable

Specify an analysis schema as a JSON string to build a custom Lucene analyzer, which transforms the input column(s) into a sequence of tokens in the output column. See LuceneTextAnalyzer for a description of the schema format.
