Sorry slight correction for the code below: I was actually using the
WhitespaceAnalyzer, not the StandardAnalyzer in constructing the
NGramAnalyzerWrapper.

Hi,
In Lucene, I'm trying to perform word-level bi-gram query parsing using
NGramAnalyzerWrapper. I'm couldn't get any word pairs in the parsed query
and I was wondering what I should do to make this work. I'm using Lucene
2.2.0
I'm using the files from: https://issues.apache.org/jira/browse/lucene-400
My code is:
NGramAnalyzerWrapper analyzer = new NGramAnalyzerWrapper(new
StandardAnalyzer(), 2);
QueryParser p = new QueryParser("info", analyzer);
Query query = lyricsParser.parse("this is my query");
System.out.println(query.toString());
When I run this, I get the following output, which has no bi-grams:
lyrics:this lyrics:is lyrics:a lyrics:query
Thank you for your help!
Stanley
