How to instruct StandardAnalyzer in Lucene to not to remove stop words?

问题

Simple question : How to make Lucene's StandardAnalyzer not to remove stop words when analyzing my sentence ?

回答1:

The answer is version-dependent. For Lucene 3.0.3 (current), you need to construct the StandardAnalyzer with an empty set of stop words, using something like this:

Analyzer ana = new StandardAnalyzer(LUCENE_30, Collections.emptySet());

Update: the answer is version-dependent. For Lucene 4.0, use:

Analyzer analyzer = new StandardAnalyzer(Version.LUCENE_40, CharArraySet.EMPTY_SET);

Note that the StandardAnalyzer is not in the lucene-core jar, but in lucene-analyzers-common-4.0.0.jar

For Lucene 6.0.0, use

StandardAnalyzer analyzer = StandardAnalyzer(CharArraySet.EMPTY_SET);
