我想在jython27中使用apache lucene。要做到這一點,我設置CLASSPATH:jython和lucene未能獲得標準模塊來創建StandardAnalyzer
% echo $CLASSPATH
/opt/lucene-4.5.0/core/lucene-core-4.5.0.jar:/opt/lucene-4.5.0/queryparser/lucene-queryparser-4.5.0.jar:analysis/common/lucene-analyzers-common-4.5.0.jar:/opt/lucene-4.5.0/demo/lucene-demo-4.5.0.jar
我發現someexamples,我試圖效仿。但是,它無法導入標準模塊以獲得StandardAnalyzer()。
>>> from org.apache.lucene import analysis
>>> dir(analysis)
['Analyzer', 'AnalyzerWrapper', 'CachingTokenFilter', 'CharFilter', 'NumericTokenStream', 'Token', 'TokenFilter', 'TokenStream', 'TokenStreamToAutomaton', 'Tokenizer', '__name__', 'tokenattributes']
>>> from org.apache.lucene.analysis import standard
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name standard
有人想法出了什麼問題嗎?
