The org.apache.lucene.analysis.standard
package contains three
fast grammar-based tokenizers constructed with JFlex:
StandardTokenizer
:
as of Lucene 3.1, implements the Word Break rules from the Unicode Text
Segmentation algorithm, as specified in
Unicode Standard Annex #29.
Unlike UAX29URLEmailTokenizer
, 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
,
StandardFilter
,
LowerCaseFilter
and StopFilter
.
When the Version
specified in the constructor is lower than
3.1, the ClassicTokenizer
implementation is invoked.ClassicTokenizer
:
this class was formerly (prior to Lucene 3.1) named
StandardTokenizer
. (Its tokenization rules are not
based on the Unicode Text Segmentation algorithm.)
ClassicAnalyzer
includes
ClassicTokenizer
,
StandardFilter

LowerCaseFilter
and StopFilter
.
UAX29URLEmailTokenizer
:
implements the Word Break rules from the Unicode Text Segmentation
algorithm, as specified in
