java - Lucene - default search lemmatization/stemming -

-

does lucene default search lemmatization/stemming on words?

for example when using code in sample, words in docs used or transformed basic form (i.e. managing -> manag), , if default lemmatizer use?

the sample referred in post uses lucene standardanalyzer not stemming.

if want use stemming, need use other analyzer implementation e.g.: snowballanalyzer
