## Package org.apache.lucene.analysis.standard Description

Fast, general-purpose grammar-based tokenizer `StandardTokenizer` implements the Word Break rules from the Unicode Text Segmentation algorithm, as specified in Unicode Standard Annex #29. Unlike `UAX29URLEmailTokenizer` from the analysis module, URLs and email addresses are not tokenized as single tokens, but are instead split up into tokens according to the UAX#29 word break rules.
`StandardAnalyzer` includes `StandardTokenizer`, `LowerCaseFilter` and `StopFilter`.
