Lucene-默认搜索词条化/词干

Question

Does Lucene default search do lemmatization/stemming on the words?

For example when using the code in this sample , are the words in the docs used as is or are they transformed to their basic form (ie Managing -> manag), and if so what default lemmatizer does it use?

Answer 1

The sample referred in your post uses Lucene StandardAnalyzer which does not do stemming.

If you want to use stemming, you need to use an other Analyzer implementation eg: SnowballAnalyzer
