Class LowerCaseTokenizerFactory

java.lang.Object

org.apache.lucene.analysis.util.AbstractAnalysisFactory

org.apache.lucene.analysis.util.TokenizerFactory

org.apache.lucene.analysis.core.LowerCaseTokenizerFactory

All Implemented Interfaces:

MultiTermAwareComponent

public class LowerCaseTokenizerFactory
extends TokenizerFactory
implements MultiTermAwareComponent

Factory for LowerCaseTokenizer.

 <fieldType name="text_lwrcase" class="solr.TextField" positionIncrementGap="100">
 <analyzer>
 <tokenizer class="solr.LowerCaseTokenizerFactory" maxTokenLen="256"/>
 </analyzer>
 </fieldType>

Options:

• maxTokenLen: max token length, should be greater than 0 and less than MAX_TOKEN_LENGTH_LIMIT (1024*1024). It is rare to need to change this else CharTokenizer::DEFAULT_MAX_WORD_LEN
