Ranjit,
The problem is definitely the analyzer you are passing to QueryParser or
MultiFieldQueryParser, and not the parser itself.
The following tests succeed using KeywordAnalyzer, which is a pass-through
analyzer (the output is the same as the input):
public void testSharpQP() throws Exception {
Analyzer analyzer = new KeywordAnalyzer();
QueryParser qp = new QueryParser
(Version.LUCENE_30, "default_field", analyzer);
assertEquals("+c# +.net", qp.parse
("c# AND .net").toString("default_field"));
}
public void testSharpMFQP() throws Exception {
Analyzer analyzer = new KeywordAnalyzer();
String[] fields = { "one", "two"};
MultiFieldQueryParser mfqp = new MultiFieldQueryParser
(Version.LUCENE_30, fields, analyzer);
assertEquals("+(one:c# two:c#) +(one:.net two:.net)",
mfqp.parse("c# AND .net").toString());
}
